Hi guys, I got a matrix C,
>>C = [{1} {2} ; {'@CF'} {2}]
C =
[ 1] [2]
'@CF' [2]
>>whos C
Name Size Bytes Class Attributes
C 2x2 478 cell
How can I transfer C into double so that:
>>C
C =
1 2
NaN 2
I've tried Str2double(C), it doesn't work. It returns,
NaN NaN
NaN NaN

Of course STR2DOUBLE does not work, because the elements of your cell matrix are not strings.
Btw, you can write the cell tighter as: {1, 2; '@CF', 2}

Your C already contains numbers, so those cells are invalid for str2double
C(~cellfun(@isnumeric,C))={nan}
