normcdf error

Dear all,

All seemed to be working well with my code until all of a sudden I received the following error message:

??? Undefined function or method 'erfc' for input arguments of type 'double' and attributes 'full scalar
complex'.

Error in ==> normcdf at 68
p = 0.5 * erfc(-z ./ sqrt(2));

I am not certain what had happened as I was entering similar values and all was working well

Do you know the z value at which this happened?

Are you attempting to input a complex number into normcdf?

erfc() only accepts real-valued input arguments. If you are not, please show what you are inputting into normcdf()
