I have three arays: I want to plot B(x axis) and C(y axis).if there is a nan in any of A,B or C that cell should be deleted with its corresponding cells in other arrays.

A=[ nan 2 3; 4 3 nan; 5 3 2] B=[ 9 8 7 ;6 nan 5;6 5 8] C=[3 4 nan;4 3 2;5 3 2]

answer: B=[nan 8 nan;6 nan nan;6 5 8] C=[nan 4 nan;4 nan nan;5 3 2]

在 MATLAB Online 中打开

nanIdx = find( isnan(A) | isnan(B) | isnan(C) );
A(idx) = NaN; B(idx) = NaN; C(idx) = NaN

Thanks! How to remove these NaN values?

What do you mean by remove them?

You have a 2d array so unless you use a cell array containing empty cells you can't just get rid of elements of a 2d array while retaining its 2d structure.
