There is a large matrix that is used in Ax=b type problem.A is symmetric. Is there any algorithm to let us save only half of the matrix a开发者_开发知识库nd do operation like x=A\\b on it?You\'ll only
I am using matrix to translate/scale an ImageView, after setImageMatrix, the result is shown directly, is there anyway to make it animated?
i\'m facing a problem right now, i need to count the number of time a certain MxM matrix appears inside a NxN one (this o开发者_如何转开发ne should be larger than the first one). Any hints on how to d

Ax, Ay, Az: [N-by-N] B=AA(a dyadic product) It means : B(i,j)= [Ax开发者_开发问答(i,j);Ay(i,j);Az(i,j)]*[Ax(i,j) Ay(i,j) Az(i,j)]
I have a 10 by 10matrix. I want to开发者_开发技巧 form a sub-matrix from this main matrix, using all the rows and columns except the 1st, 2nd and 8th columns and rows.
I have a dataset that I need to report as a matrix. Within the dataset, I pull together the individual totals for CDNs within a week, along with the overall total for all CDNs within the week. I do th
I\'ve tried many formulas and conversions, but nothing gave me the result I expect. The scenario is very simple:
In the middle of a c++ code, eclipse, I need to compute the multiply of matrices A and B, with the size of 2400*3600 (so the dimensions are not the same). The matrices are stored in float two dimensio
How to efficiently combined cell array vectors with different length into a matrix, filling the vectors to max length with 0s or NaNs? It would be a nice option for cell2mat().
