How to plot a contour plot with the next data

Hello everyone! I have been trying to plot some data within an equation, but I have not been able to figure it out.
In my X-axis I should have a linspace(0.28,0.4,9)
In my Y-values I should have linspace(1200,1400,9)
My Z values are this equation:
Z=2077+79.5A-76.3B
Where A=[-1 1 -1 -1 1 -1 1 1 0]
& B=[1 -1 1 -1 1 -1 -1 1 0]
Can someone help me with this? From what I have read I know that it should use meshgrids and it should be very simple but I am not very familiarized with the topic. Thank you!

Hello Sebastian, I assume A is the x-parameter, B is the y-parameter?
x = linspace(0.28,0.40,9);
y = linspace(1200,1400,9);
A = [-1 1 -1 -1 1 -1 1 1 0];
B = [1 -1 1 -1 1 -1 -1 1 0];
[X,Y] = meshgrid(A, B);
Z = 2077 + 79.5*X - 76.3*Y;
figure
contour(Z)
set(gca,'XTickLabel',num2str(x'))
set(gca,'YTickLabel',num2str(y'))
