The same value in the matrix

Hi,

I am MathCad beginner. I'd like ask a question: How can I link value of one matrix element with another element at the another position. (For example in the Excel: I have the cell A1 where i wrote number 5 and I want the same value for the cell B2. So I will write =A1 to the B2 - Is it possible something similar in the MathCad?

thx for answering

Steve
