Error showing that input arguments are double.

I have written a program to compare two binary images. Both inputs are logical. But when I run the program it says "Undefined function 'ccc' for input arguments of type 'double". What does it mean and what I have to do? Please help me.

We would need to see your code.

What shows up if you use

which ccc

?

MATLAB converts logical variables to real doubles if you use them to calculate:

a = true;
b = true;
c = a + b

c =
     2

class_a = class(a)
class_b = class(b)
class_c = class(c)

class_a =
logical

class_b =
logical

class_c =
double
