building an array

[FlyingKiwi]

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

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.

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

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.

No worries. Little problems can only ever waste little amounts of time

That is an excellent point. I completely missed that

I deserve a.....

[RichardJ]

Well, then I guess I would also deserve one for missing vlookup

Ok Richard you where correct.

Didn't understand why the thread was talking about a matrix though.
