For loop

I have defined function with "for loop" inside for table content processing. It looks simple, but unfortunately it doesn't work. Instead of calculation results , the message  "This value mus be a scalar a matrix" is being displayed.

I was using this function with Mathacad 15 and it was working fine, but I can't reproduce it within Mathcad Prime 8.

Where did I go wrong?

 

Regards,

Bogdan

ttokoro already pointed you to the error.

You had an implicit multiplication between "(rows)" and "N.t.".

It should read "rows(N.t.)" instead!

Now you should get the expected result:

You can achieve the very same result without any utility function in one go using a boolean comparison and vectorisation

Another option is using a simpler utility function, written to be used with just one scalar and called vectorized.

Here are two example for that kind of utility function
