I am new to MathCAD so I am guessing this is a pretty basic question. I want to build an array based on a larger array. I can get it to work for a single vector, but as soon as I add another column to make a matirx, it doesn't work. Anyone able to let me know what I need to do to fix it? I have attached my file.

Thanks for helping me

in the line containing your if statement:

if x[i,0 <-- m

replace the local assignment operator <-- with a boolean equals (Ctrl =):

if x[i,0 = m

Firstly, welcome to the forum.

Its not very clear exactly what your after. You could try expanding your explanation or manually type an example of the array you want to create.

I doubt that is what he's after Richard. If is it it seems a little over the top, could just use the vlookup function.
