Hi

The variable “Throughput” is defined in two ways in your code

Throughput=B.*log2(1+(10.^(SNIR(end)/10)));

Throughput=Throughput.*(B.*log2(1+(10.^(SNIR(end)/10))));

Make sure that you defined it properly. Moreover, this variable is a scalar since you used SNIR(end), hence it cannot be plotted unless it is an array of values.

"hence it cannot be plotted unless it is an array of values."

Actually scalars can be plotted, but because the default LineSpec has no markers the points are not visible... but the points can certainly be plotted without error (i.e. the line objects will exist, even if they do not show in the axes).
