I have a matrix I am trying to plot called "errors"
Best I can do is:
plotmatrix(errors,'b')
But that gives a weird mess of graphs:

The bottom left one is what I am shooting for.
Thank you.

Plot Matrix isn't a plot function for a matrix, it provides a matrix of different plots. You'll want to use the standard plot function, can you provide some sample data?

Given your figure it looks like you have a two-column matrix. The bottom left plot one is given by:
plot(your_data(:,1),your_data(:,2));
The top right:
plot(your_data(:,2),your_data(:,1));
The diagonals:
hist(your_data(:,1));
hist(your_data(:,2));
You get the idea...
