Convert matrix to cell and replace NaN with '-'

Question

I have a matrix A

A = [nan nan 1 0 nan]

How do I convert matrix A to cell, and replace nan with '-', so a new B cell array will look like this:

B = {'-' '-' 1 0 '-'}

I tried

A = mat2cell(A);

or

A = num2str(A);

then

A(cellfun(@isNaN,A,'uniformoutput',false)) = {'-'};

This is not working.

Answer 1

I think you can try num2cell

B = num2cell(A);
B(cellfun(@isnan,B)) = {"_"};

which gives

>> B
B =
{
  [1,1] = _
  [1,2] = _
  [1,3] =  1
  [1,4] = 0
  [1,5] = _
}
