Working with Matrices in MathCad
Working with Matrices in MathCad
(OP)
Hi,
Hoping someone here can help..
I have a equation, say: P=(q*t^a)/S
I want to vary P with t and I would like to populate the first column of an array with t values, say 1..75 (range variable) and then populate the second column with P assuming q, a and S are static. Then I would want to find the time, t at which the pressure, p fell below a certain value.
How do I do this? I can find plenty on how to mess about with an array (transposition, etc.) but not much on how to work with one with equations.
Thanks,
James

P[k := (q * t[k *a)/S

Or do you have to create seperate arrays and Append them together?
Thanks, james

RE: Working with Matrices in MathCad
Recent versions of Mathcad will not allow you to mix units within a matrix, so you would have a single column array t, consisting of 76 values, and a column array P, consisting of 76 corresponding values. You can stick everything in a two-column array if you are willing to divide out the units, but units are what Mathcad excels at.
