Hello,
I want to make a plot for a presentation that will show the errors and I don't know how to do this in a "professional" way.
For examample I have matrix A (3 x 8) column 1 is X, column 2 is Y and column 3 is Z. Matrix A represents the "ground truth". And matrix B, same size, which resulted from calculations. B should be very close to A as values..But how I can show that?

Lets say the reference values are A=[ 2 3 4 5 6]. I got B=[1.9 2.7 4.2 5.1 6.3].
the error matrix is E=A-B ..How I can make a graph/plot showing how big or small are the errors?

Ciuban, how about simply
plot(A-B,'bd')

That might do it. But lets say the plot of A is a line, I want to plot the errors around that line.

Not quite sure I understand... something like this?
hold all
plot(A,'r-')
plot(B,'bs')
How do you need this plot to be adapted to fit your needs?
