Description
surfht(Z)
is an interactive contour plot of the matrix Z treating the values in Z as height above the plane. The x-values are the column indices of Z while the y-values are the row indices of Z.
surfht(x,y,Z)
where x and y are vectors specify the x and y-axes on the contour plot. The length of x must match the number of columns in Z, and the length of y must match the number of rows in Z.
There are vertical and horizontal reference lines on the plot whose intersection defines the current x-value and y-value. You can drag these dotted white reference lines and watch the interpolated z-value (at the top of the plot) update simultaneously. Alternatively, you can get a specific interpolated z-value by typing the x-value and y-value into editable text fields on the x-axis and y-axis respectively.
