Hello Probably the functions you're using have variables that haven't been defined as numbers. For example , if you try: In[112]:= FindMinimum[a*x^2, {x, -1}] FindMinimum::nnum : The function value 1.a is not a number at {x} = {-1.} This is because Mathematica can't know what is the value of "a" because it hasn't been defined before, so it can't find a minimum etc.. Please send more information about your specific problem, so we can be more helpful...
