- The LAMB toolbox
- License: Freeware
- Price: 0.00

Description: This program is based on the Ph.D. thesis[1]: "LAMB: a SIMULATION TOOL for AIR-COUPLED LAMB WAVE BASED ULTRASONIC NDE SYSTEMS" from The Polytechnic University of Catalonia (UPC), Department of Electronic Engineering (EEL) 2010. The software simulates the behaviour of an entire air-coupled ultrasonic Non-Destructive Evaluation (NDE) system based on 1D linear array transducers.

- Cumulative Mean and Variance
- License: Freeware

>> Y = cummean(X,DIM); if X is MxN, Y is also MxN. To illustrate the functionality, lets assume X is a 1xN vector. Then, Y is a 1xN vector where the n-th entry in Y is given by mean(X(1:n)). So, Y(end) = mean(X), and Y(1) = X(1). cumvar works in the same way, and this can be done on an arbitrary dimensional X along dimension DIM.

This is a very simple function to find the local maximum in any dimensional array. As simple as it is it still gives nice results. I use the imdilate() function as a maximum operation and then compare the data to the result. The function receives three parameters: the data, a vector defining the minimum distance between peaks in each of the data dimensions.
