Using Multiple Variables to Create the Surface
Occasionally, you may need to provide coordinate data for a surface view in two separate variables. If you choose to provide x and y variables, they are used by the WzSurface Tool to determine the x and y coordinates of the gridded z data. The WzSurface Tool generates x and y tick labels using the range of the x and y variables.
Each of the allowed WzSurface Tool variables is discussed below:
z—A 2D array containing the values that make up the surface. If you supply x and y variables, the surface is plotted using the coordinates specified by the values in the x and y variables. If you do not supply x and y variables, the surface is generated using the array indices of each element of the Surface Data variable.
x—(optional) A vector or 2D array specifying the x coordinates for the surface.
If
x is a vector, each element of
x specifies the
x coordinate for a column of
z. For example,
x(0) specifies the
x coordinate for
z(0,*) (i.e., all elements in the first column of
z).
If
x is a 2D array, each element of
x specifies the
x coordinate of the corresponding point in
z. For example,
x(5,5) specifies the
x coordinate for
z(5,5).
y—(optional) A vector or 2D array specifying the y coordinates for the surface.
If
y is a vector, each element of
y specifies the
y coordinate for a column of
z. For example,
y(0) specifies the
y coordinate for
z(*,0) (i.e., all elements in the first row of
z).
If
y is a 2D array, each element of
y specifies the
y coordinate of the corresponding point in
z. For example,
y(9,9) specifies the
y coordinate for
z(9,9).
