I am not getting the plot graph for this equation.

3 views (last 30 days)
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.

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.)
