# Plotting arrays with different sizes

I want to plot a function where the arrays are different sizes
gamma = [1, 1.2, 1.4, 1.6, 1.8, 2];
x = [0:0.01:2000];
b = 349.22567;
y = 2.*(gamma.^2 - x./b);
Arrays have incompatible sizes for this operation.
How can I do this? Obviously
arrays have incopatible sizes
so this will not work. It would be unwise at best to do
plot(x, 2.*(gamma(1)^2 - x./b), 'b')
% etc...

Transpose ‘gamma’ to create a family of curves —
gamma = [1, 1.2, 1.4, 1.6, 1.8, 2];
x = [0:0.01:2000];
b = 349.22567;
y = 2.*(gamma(:).^2 - x./b)
y = 6×200001

A slightly different version —
gamma = [1, 1.2, 1.4, 1.6, 1.8, 2].';
x = [0:0.01:2000];
b = 349.22567;
y = 2.*(gamma.^2 - x./b)
y = 6×200001
