Find the minimum and maximum of 2D cell matrix, which may contain nested cell or numeric arrays. These three functions calculate the minimum and maximum of all numbers within a 2-dimensional cell (or numeric) matrix. The cell matrix may contain other cell matrices, or numeric matrices, or a mix of them. The contained cell matrices may in turn contain others, etc. The search is performed by nested calls, therefore the same applied to all levels of nesting. This function can be of use when searching for the minimum and maximum coordinates of all graphics objects in a plot.

- Normalize N-D Vectors in Single Matrix or N Component Matrices
- License: Shareware
- Price:


Normalizes N-D vectors provided either in one matrix, or as multiple component matrices. NORMVEC normalize vector(s). NORMVEC computes the unit vectors in the direction of the vectors provided. It can process two types of arguments: 1) single matrix of vectors 2) multiple matrices of vector components (as those returned by MESHGRID and NDGRID) In both cases, the p-norm to be used can be specified. The default is the 2-norm (Euclidean). Only in the first case, the matrix dimension along which the vectors are defined can be defined. The default is the first non-singleton This behavior is derived from VNORM (FEX id=#10708, by Winston Smith), which is called by this function. Zero vectors are normalized to 0 and NOT to NaN. usage Case A: matrix of N-dimensional column vectors [v] = NORMVEC(v) [v] = NORMVEC(v, 'p', n)...

- Price:


PLOTMD(AX, X, VARARGIN) plots the points in matrix X in the axes with handle AX using the plot formatting options in VARARGIN. X must be a matrix whose columns are the 2D or 3D vectors to plot. If the column vectors are N-dimensional, then only the first 3 components of each vector are used in the plot. For usage information please type "help plotmd".

- plot 2/3D vector(s)
- License: Shareware
- Price:


Plots 2D or 3D vectors at points, both provided as matrices of column vectors. QUIVERMD(AX, X, V, VARARGIN) plots the column vectors in matrix V at the points with coordinates the column vectors in matrix X, within axes object AX using plot formatting options in VARARGIN. Example x = linspace(0, 10, 20); y = linspace(0, 10, 20); [X, Y] = meshgrid(x, y); x = [X(:), Y(:) ].'; v = [sin(x(1, :) ); cos(x(2, :) ) ]; quivermd(gca, x, v) For usage information please type "help quivermd".
