MATLAB: Have two columns that are the same size but one of them has NAN on the first and last row, how would i delete those rows for both columns

Question

code is this:

[rows, cols] = find(isnan(Fe));

Fe(:,unique(rows)) = [];

WAT(:,unique(rows)) = [];

error message is:

Matrix index is out of range for deletion.

Error in Comparison (line 204)

Fe(:,unique(rows)) = [];

Answer 1

a = 1:10;
b = 1:10;
b(1) = NaN;
b(end) = NaN;
NaN_Vals = find(isnan(b));
a(NaN_Vals) = [];
b(NaN_Vals) = [];
