Plot one column matrix in range

Hello, I have a matrix with one column [20x1] and I want to plot it, but so that all 20 results are evenly distributed. For example, I want to plot all 20 matrix elements from 0 to 10 on the x-axis.

I tried to do this way:

figure(1);
plot(20,matrix)

And I saw blank figure

y=matrix;
x=linspace(0,10,numel(y));

plot(x,y)
