## Normalize eigenvec in MathCAD prime

Hi,

I have attached my problem.

I need to convert the matrix to look like the "b" part. I get the "a" part correctly.

The operation is represented in excel file. I really dont know how to do it or if it is possible to do in MathCAD.

Really appriciate any helt.

 Can you please update my mathcad file with the solution?

Here you are.

I also added a way to create that function which does not need programming  (yellow) and so can be used in Prime Express, too.

Furthermore two ways to create the desired matrix U without using a user function "eigenVector" (blue, violet).

The last method would be the preferred way to do it in Prime as it does not call "eigenvec" twice.

The eigenvectors are normalized.

So how can i get the matrix to be like the one i called "The correct value"?

How do you write this in mathcad? i cant write the "<---"

Can you please update my mathcad file with the solution?

Its in the Programming menu and thats only available in the paid for version.

Are you using the free Prime Express version?

I use the paid version.

Then you can find the local assignment arrow on the "Math" ribbon, area "Operators and Symbols"  in the "Programming" menu.

Find in my answer below the file along with a few other ways to achieve the same effect.
