Asked by maharaj on 2 Apr 2013

s=A+((B*exp(-1.001*((x.^2) + 100)))/((x.^2) +100)) This is the equation I am working on I have x ranging from -20 to 20 in steps of 2 and I think the problem is with the constants being very small. A= 10^-10 B=10^-3

Graph is not being generated. Would someone help in generating the graph for this.

Accepted answer

Presumably you want array division instead of a LS solution. Try

s=A+((B*exp(-1.001*((x.^2) + 100)))./((x.^2) +100)) % Note the dot right here ^

That gives you a vector instead of a scalar. Plots of scalars tend to be rather boring. (The `plot` function does draw a single point, but it's often easy to miss.)
