the isnumeric function and the NaN
26 views (last 30 days)
I have a matrix array (A) that includes three column arrays. All columns contain integers except that one of the columns also include NaNs. When I type isnumeric(A), the output is a logical value 1. Apparently NaN is recognised as a numeric entry as otherwise MATLAB would return a logical value of 0. How is a NaN recognised exactly?
