Having a problem here, every time i try to perform a simple matrices multiply function, it shows as invalid array index , but surprisingly the same thing has worked in other systems.Please help. Have tried defining everything separately but the problem persists.

You seem to number the elements of a vector or matrix starting by 1 for the first element.

By default Prime starts by 0 for the first entry.

That behaviour is controlled by the system variable ORIGIN.

Chances are that you forgot to set ORIGIN from the default value 0 to 1.

You should attach the (Prime) worksheet, not just a picture. And please tell which version of Prime you are using,

 

Success!

    Thankyou. The changing the Default value of Origin worked.
