I need to convert my matrix [648x2400 double] into integers value to use a mRMR function, but I do not know how to do that. I have tried to convert by uint8(matrix) or int8(matrix) but it does not give integers... And I always have this note: "Undefined function 'mrmr_mid_d...
Hi, I am trying to convert a string to a double precision number using str2double. Since my string has leading zeros, i.e., '-0,01298784', when I convert it to double, it comes like -1298784. How can I make sure the leading zeros are still t...
