• Zero Padding 2^N
• License: Freeware
• Price: 0.00
• 

zeroPadding2N makes zero padding of a given array to a 2^N length. X_ = zeroPadding2N(X), for array X, returns the array with the necessary appended zeros so it reaches the next power of 2 length. X_ = zeroPadding2N(X, N), for array X, returns the array with the necessary appended zeros so it reaches the next 2^N length. Example: If X = [1 2 3]; then X_ = zeroPadding2N(X) returns X_ = [1 2 3 0] X_ = zeroPadding2N(X, 3) returns X_ = [1 2 3 0 0 0 0 0] X_ = zeroPadding2N(X, 1) returns X_ = [1 2 3].

• Remosaic of RGB image array
• License: Shareware
• 

Interleaves the color pages of an MxNx3 color image array into presumably what was the original, 2Mx2N, intensity output of a Bayer image sensor. Useful for capturing a monochromatic image (like actively illuminated IR) with a color sensor (like a cheap color webcam). It does not compensate for effects due to demosaic or any image processing done between the image sensor array and this function..

• ASSIGN VARIABLE NAMES TO MULTIDIMENSIONAL ARRAY AND SAVE
• License: Shareware

The script solves the problem of assigning a variable name that changes with each iteration, while saving the result using a for loop. It uses a multidimensional array as input and produces matrices as outputs (ASCII)..

• Label connected components in 2-D array
• License: Shareware
• 

LABEL is a generalization of BWLABEL: BWLABEL works with 2-D binary images only, whereas LABEL works with 2-D arrays of any class. L = LABEL(I,N) returns a matrix L, of the same size as I, containing labels for the connected components in I. Two adjacent components (pixels), of respective indexes IDX1 and IDX2, are connected if I(IDX1) and I(IDX2) are equal. N can have a value of either 4 or 8, where 4 specifies 4-connected objects and 8 specifies 8-connected objects; if the argument is omitted, it defaults to 8. Important remark: ----------------------- NaN values are ignored and considered as background.

• Write a cell array to a text file
• License: Shareware
• 

This function enables you to directly write data from a cell array into a text file, which functions like FWRITE and FPRINTF do not. Usage: fwritecell(filename, format, data) writes cell array "data" to the file with name "filename" using the C language conversion specifications in argument "format". The conversion specifications are the same as those used by SPRINTF. fwritecell(filename, data) writes cell array "data" using a fixed width format padded with whitespace. The field widths are determined automatically. Note that the decimal point for floating point numbers may not be aligned within columns.

• Plot a 3D array using patch
• License: Shareware
• 

USAGE ===== This function enables a 3D array to be displayed using a patch surface mesh. To plot a 3D logical array, the function is called using the following syntax: >> hpat = PATCH_3Darray(gridINPUT,gridX,gridY,gridZ); Alternatively, a 3D numeric array can be plotted such that the colour of each facet corresponds to the value of each voxel in the array. The plot is generated using either of the following commands. (Note that voxels which are not to be displayed should contain a value of NaN.) >> hpat = PATCH_3Darray(gridINPUT,gridX,gridY,gridZ,'col'); >> hpat = PATCH_3Darray(gridINPUT,gridX,gridY,gridZ,'sym'); The colormap to be used for the display of a 3D numeric array can also be defined as follows: >> cmap = jet(16); >> hpat = PATCH_3Darray(gridINPUT,gridX,gridY,gridZ,'sym',cmap); INPUT PARAMETERS...

[M L] = routh_hurwitz(P,N) This function gives the Routh's array from a numerical or SYMBOLIC polynomial and includes two special cases: (1) the first element of the row is zero; (b) a row of zeros. P Numerical or symbolic array of coeficients. In the case of symbolic variables it is necesarry to define them as: >> syms a b c ... N Digits to be considered zero a number. E.g, for N=5, 10^(-5) is considered a zero. By default, N=10 M Routh's array without any simplification (e.g., with epsilon notation) L Simplified first column of Routh's array with simplification (e.g., using the limit when epsilon tends to zero) that determines the number of roots in the right-half of the s-plane: the number of changes of signs in L Examples: 1.

[M, L] = jury(P,N) This function gives the Jury's array from a numerical or SYMBOLIC polynomial and includes the two special cases: (1) the first element of the second row of a block is zero; (b) a row of zeros (when there are roots on unit circle or reciprocal roots like (r,1/r). The symbolic results can be used to solve inequalities and obtain the stability intervals of symbolic vaiables. P Numerical or symbolic array of coeficients. In the case of symbolic variables it is necesarry to define them in workspace as: >> syms a b c ... N Digits to be considered zero a number. E.g, for N=5, 10^(-5) is considered a zero.

Create a new type called STR with a character array inside, implemented as a structure. It was inspired in Visual Basic syntax. It was implemented several operators and functions overloads, but allows any character array function using "char" conversor function or ' transpose overload. It's necessary to create a folder from a MatLab folder in one of the MatLab paths. The folder name is class name, with @ prefix. The .m name is class name. Operator Overload: ==,~=,=,>,< -,*,/,,', [], +,-, (), | Function Overload: disp, length, upper, lower, strfind Other Functions: str, left, right, mid, padl,padr, padc, instr, repeat, replace, trim, ltrim, rtrim Example ======= s1=str('play'); s1-'l'+ ' t' + 'cricket' - 'cr' ans= pay ticket More details in the start of str.
