PCA problem and Memory error
Hello, I have a matrix, size of 160x162x10. I want to reduce its dimension. I used codes below: samp_pca=reshape(samp,[160*162 10])'; [COEFF,SCORE] = princomp(samp_pca); But it produces "Out of Memory" error on MatLab 2010a. I increased the physical memory of Windows 7.

Help with Bootstrapping Function
My question concerns the output of the bootstrp function. The bootstrap function is as follows: BOOTSTAT = BOOTSTRP(NBOOT,BOOTFUN,D1,...) If BOOTFUN has more than one output (i.e. [P,S] = POLYFIT(X,Y,N)) how to do I get BOOTSTAT to display all of the outputs (i.e. BOOTSTAT = [P,S])? Thanks, Nate ... 30 Jul 2010 14:04
