Help needed: Two Dimensional Interpolation
Hi, I have a question about two-dimensional interpolation. I know in Matlab you could use interp2 to do the two dimensional interpolation. But you have to mesh grid before doing so. If I have a very large matrix (e.g. 500,000x3 [X Y Z]) and I want to interpolate from this large matrix. For example, interp2(X,Y,Z,x1,y1)... 13 Jul 2010 16:26

The .m file by m vichi (see below) works but also messes up my y labelling function ax2 = ticklabel(ax1) % TICKLABEL Shift the tick labels in ... 13 Jul 2010 15:19

Image Processing: How to remove shades/reflection/shadow on an image

does matlab support php code
Hy Mohamed, I've trying to do this too. But I didn't find nothing about this. But you can copy all weights, bias and transfer funcions to php code and make and "simulation" code in php. Look, you have to take care about "preprocess" (mapminmax) normalizations. I needed to deactive "mapminmax" becouse my normalizati... 13 Jul 2010 15:19

how to generate all vectors of length n with entries are 0's or 1's then sum over
Hi, I need your help for this problem, please. \mathop {\sum {...\sum }}\limits_{z_r \in {Q_{2}^{*}}} such that Q_{2}^{*}=\{(z_1,...,z_r):z_{j}=0,1,\sum_{j=1}^{r}z_{j}=\ell\}, where \ell = 0, 1, . . . , r. For example. If r=3, \ell=1; then we are looking for triples with elements 0's or 1's and sum to 1 i.e... 13 Jul 2010 19:43
