y=mod(num,den)
Inputs  
num 
Any real array. 
den 
A real array of the same size as the input. 
Outputs  
y 
An array of the same size as the inputs. Each element of the output is the result of applying the mod operator to the corresponding elements of
the inputs. However, when an element den[i] is zero, the corresponding
element of y is set to the element num[i] .
