The MATLAB user has this: clear clc M(:,:,1) = [1,2;3,4]; M(:,:,2) = [21,22;23,24]; J = [1,2; 2,1]; They want this: ans = [1 22 23 4] They tried this: D = M(:,:,J) % This doesn’t… 更多内容 >>

I recently got an e-mail from a MATLAB user that had a large dataset in Excel. They wanted to import the data and “take the average of the graph”. It turns out that meant fitting a… 更多内容 >>

This puzzler is very straightforward, so I hope to hear from some of the newer MATLAB users. I think the solution is very linear, most people would come up with the same solution. As a hint, be… 更多内容 >>
