Hi,
I have 4 x 202 matrix, and I want to plot the columns in 2's e.g columns 1 and 2, next columns 3 and 4 as they represent X and Y coordinates. How can I do this?
Thanks

First a (4 x 202) matrix defines a matrix of 4 rows and 202 columns. Assuming that it’s actually a (202 x 4) matrix, perhaps something like this —
M = randn(15, 4) % Prototype
Mr = reshape(M, [], 2)
figure
plot(Mr(:,1), Mr(:,2), '.')
If the matrix actually is (4 x 202), transpose it first, then use the approach in this code example.
.

x = rand(202, 4); % 202x4 (not 4x202)
plot(x(:,1), x(:, 2), 'ro', x(:,3), x(:, 4), 'b*')
