Double inputs must have integer values in the integer range when mixed with integer inputs

I have attached the matlab code file. When i run Encryption_Decryption_total_process.m file. It gives the following error:

Double inputs must have integer values in the integer range when mixed with integer inputs.

Error in Encryption_Decryption_total_process.m (line 118)

xorr1(1,i)=bitxor(column_image(i),m(i));

Can any correct this error.
