Hi all, I have matrix A and C as follows.How to do the function that deletes the columns whose last two values of matrix A are NaN and at the same time delete the same columns in C ? Results expected: a is the new matrix after we delete the columns from A as required. c is the new matrix after we delete the columns from C, with deleted columns indexed as those from A...
a = A(:, ~isnan(a(end-1,:)) | ~isnan(a(end,:)))
helps to get the following results. But I don't know how to get the index of the deleted columns from A so that I can work on C.Thanks.
A =
1 NaN 1 1
1 1 1 1
NaN NaN NaN 1
NaN NaN 1 NaN
a =
1 1
1 1
NaN 1
1 NaN
