Assuming your 3D plot was created by a vector of x coordinates, a vector of y coordinates, and a matrix of z coordinates, if you want a 2D slice along the XZ plane, you just need to choose a slice from your z-matrix (ie, a row or a column) and plot that vector against your x-vector.

Choose the appropriate ‘X’ and ‘Z’ (or ‘Y’ and ‘Z’) values from the matrix to get a cross-section.
[X,Y,Z] = peaks(50);
figure
surf(X,Y,Z)
xlabel('X')
ylabel('Y')
figure
plot(X(24,:),Z(24,:))
grid
figure
plot(X(11,:),Z(11,:))
grid
.
