Find of solve block

Hello everyone,

I am working with Mathcad Prime 3.1, and I use the solve block.

The problem is with the function find: I want to specify directly (like in Mathcad 15 with the index) the element that should be reported. I don't want to report all the matrix and I don't want neither to use an extra variable to report the specified element of the resultant matrix.

Thanks for your support,

Best regards,

Nadia

Nadia;

The attached file was created in Prime 3.0.

Please open it in Prime 3.1, and post a screen shot of the result.

1st. Can you post the worksheet?

2nd. "and I don't want neither to use an extra variable to report the specified element of the resultant matrix" that is fundamentally impossible. If you want part of a matrix, you have to specify which part. That specification implies at least one variable (which might be a constant).

Hello LucMeekes,

I am referring to this:

The index is used directly in Find function in Mathcad 15. It is not the case in Prime 3.1.

In other terms, I want to do it in the same way than Mathcad 15.

Best regards

Nadia

So what is keeping you from typing

[ORIGIN

at the end of the Find() function, in order to get the first of the list of solutions?

(To get the second of the list of solutions, type [ORIGIN+1 instead.)

It's not clear to me what you want. You are finding two unknowns, so the result is a vector with two rows. If you want to display only one of them, just use a vector subscript.
