subscript problem

subscript problem

subscript problem

(OP)
What does it mean when you try to plot y=mx+b diagram and mathcad is complaining on subscript index([i) which is no x[i. It says "the value of subscript or superscript is too low or too small for this array"
Can not find anything wrong with what I have do. I have done exactly the same thing before and it worked.

RE: subscript problem

Make sure that ORIGIN=the starting index of
your array.  Please read the ORIGIN command !

Take care,

RE: subscript problem

(OP)
How can I solve eq below in mathcad.
Mol=x*mass, where x is four differents and mass is a constant. I need to calculate Mol for different x. All four values for x is known.

RE: subscript problem

Lots of ways

> Read the manual
> Make mol a function by defining it as mol(x):=x*mass
    assign x as a matrix of known values

RE: subscript problem

One way to s follow:

o   Constant definition:
ex.   Intercept     b=-3.1
      slope         m= 1
      Index range   i:0;3    (assume default ORIGIN:0)

o   Varibles definition:
      4 values              x[i:2,5,9,7

o   Equation definition:
       - Using index, i


            y[i : m*x[i + b

            y[i= (see result in MathCad
     - Using function
       
            Y(X): m*X + b
           
            Y(2) =   (see result in MathCad
            Y(-123)= (see result in MathCad
