在MATLAB中,可以使用find()函数来查找小数。find()函数用于查找数组中满足特定条件的元素的索引。 要在MATLAB中使用find()函数查找小数,可以按照以下步骤进行操作: 1. 创...
sort(A,2) but you are now not working with vectors returned from find(), which areindiceswith row(K) corresponding to col(K) after the find and row(K), col(K) giving the location of what was found; you are now sorting by arraycontentbased upon the full array, which is a different...

I have an Excel spreadsheet whose rows I'd like to randomly shuffle and further use in Matlab. To that end, I'm reading the XLS into a cell array, generating random numbers into a column, then sorting by that column. This is proving to be problematic though, ...
