## Re: Evaluating a string in octave

```If I interpret the question correctly, you have a string
in the variable q .. so something like

q = " 15 *  (0.5)^(K)   -35 *  (0.7)^(K)  + 20 *  (1)^(K)";
(note: strings are inside commas ".....")

in this case just type

k=5; eval (q)

```I have a string in octave that looks like this:
( it was produced with my new Inverse Z Transform function)

+ 15 *  (0.5)^(K)   -35 *  (0.7)^(K)  + 20 *  (1)^(K)

and I put this string in q

q = + 15 *  (0.5)^(K)   -35 *  (0.7)^(K)  + 20 *  (1)^(K)

Now I want to give K a value and then evaluate the formula.

K=5
m=evaluate(q)

How do you do this?

Doug
