how to plot specific column from a matrix

Hello everyone, I have a 349525 x 4 double matrix, if I try to plot the graph of column 1 vs column 4, what should my command be. I've tried plot(M(:,1),M(:,4)) already and it didn't work out. Any help will be much appreciated. Thank you.

A = rand(100,4) ; 
plot(A(:,1),A(:,4))   % plot 1 column w.r.t. 4 column

If this is not working. Show us the full error or tell us how the plot is.

Hello KSSV, yes, this is working but I don't think this answered my question. I was looking for the method of selecting 2 columns (coulmn 1 and 4) from a matrix and plot it while column 4 is on the x-axis and column 1 is on the y-axis

[KSSV]

A = rand(100,4) ; 
plot(A(:,4),A(:,1))
