Retrive horizontal matrix rows based on vector in Mathcad

Hello everyone,

I would like to retrieve certain rows of a matrix based on an initial vector:

Lets say I have the vector Lp and and I want to search the rows in the matrix M (based on the first column) in order to achieve the matrix Final.

Note that the vector Lp can have more numbers as for the Matrix M (this is just an example).

Is there a simple way to do this?

 

Thanks in advance for your help.

 

Miguel,

Prime 7 worksheet attached.   (You can safely ignore everything else that is in the collapsed Areas, I was just using this worksheet as a scratchpad for some other questions)
