How to shuffle (completely at random) big data stored in Excel file by Matlab?
I want to shuffle my data row wise (in a single unique row there will be no shuffling, it has to remain the same - I mean all individual cells in a single row can not change). The number of rows I have in my excel files is around 170000.
All I need is to shuffle randomly all the rows among them. How can I do this by mat-lab commands? Codes or algorithm please!
Solution
For reading and writing excel files see xlsread and xlswrite.
To randomly shuffle the rows of a matrix:
M = magic(5);
Mshuffled = M(randperm(size(M, 1)), :)
