Plot 2D - with third argument (colorbar)
Hi there, I have 3 vectors, 2 of them represent x,y point coordinates, and the third represents the appointed values for those points. Is it possible to plot those x,y coordinates, e.g. plot(x,y,'.') and then add a colorbar which will be connected to those values, where the colorbar is defined by the third v... 28 Jul 2010 11:51

statistical test for equal composition of a binary vector
Hi, Is there a statistical test available in matlab that will tell me if frequency of 2 elements in my binary vector do not support equal distribution. This is simply a chi-sequare test with expected frequency of 0.5 and 0.5--but I am not sure how to do this in matlab. For example, I have a vector of length 10... 29 Jul 2010 08:34

Hi Dean, two-dimensional matrices work. So far I didn't find out how three-dimensional matrices work (e.g. colour images). You need to create the 2D-array in your COM software in such a way: HRESULT hr; SAFEARRAY *pSA; float HUGEP *pFLOAT; SAFEARRAYBOUND aDim[2]; // two dimensional array aDim[0].lLbound= ... 28 Jul 2010 09:38
