MATLAB: Reshaping X, Y, Z Data

reshape

Hi,

I plotted a surface using q = surf(X_New,Y_New,Z_New_2) where X_New and Y_New are both 1×288. Z_New_2 is 288X288. I want to reshape each X_New,Y_New and Z_New_2 into n-by-1 arrays. I'm running into a roadblock with my limited knowledge of Matlab so any help or feedback would be appreciated.

Regards,

Mario

X_New = X_New(:);
Y_New = Y_New(:);
Z_New_2 = Z_New_2(:);

does what you asked - that is, it reshapes each of the arrays into an n-by-1 array. Is that what you need?

MATLAB: Rotate figure by transposing matrix in contourf problem

Transposing every matrix does not change anything. If you throw two matrices X & Y as input, then the coordinates for each Z-value is obtained from those matrices, i.e. Z(1,1) is plotted at [X(1,1) Y(1,1)]. If you transpose each matrix, then the coordinates for each Z remains the same. If you are instead throw only the Z matrix as input to contourf, then transposing it works because the Z-values are plotted against their index, i.e. Z(1,1) is plotted at [1 1].

I suppose this is what you are trying to do:

[xc,yc]=contourf(new_Y,new_X,new_Z);

Use the multiplication element by element .*

z=x.*y
x_new=x.*cosd(y)
y_new=y.*sind(y)
