How do I replace zeroes in a <logical> 0 and 1 array with NaNs?

Hey,

I have a logical array with ones and zeroes and now I would like to replace the zeroes with NaNs but can´t find the right commend.

A(A==0) = nan; NaN's cannot be converted to logicals.

A(~A) = NaN; NaN's cannot be converted to logicals.

Also tried this: A=num2cell(A);

Who can help me out?

Greetings, A matlab hero :) A=num2cell(A);

It didn't work because you were trying to replace logical values (the zeros/false) with doubles (the NaN). So first, convert the A array to double.

A = double(A);
A(A==0) = NaN; % or A(~A)=NaN

Of course A will not be a logical anymore.
