What does contour function do in MATLAB?

contour( Z ) creates a contour plot containing the isolines of matrix Z , where Z contains height values on the x-y plane. MATLAB^® automatically selects the contour lines to display. The column and row indices of Z are the x and y coordinates in the plane, respectively.

What does a contour plot show?

A contour plot is a graphical technique for representing a 3-dimensional surface by plotting constant z slices, called contours, on a 2-dimensional format. That is, given a value for z, lines are drawn for connecting the (x,y) coordinates where that z value occurs.

How do you find the contour in MATLAB?

imcontour( I , V ) draws contour lines at the data values specified in vector V . The number of contour levels is equal to length(V) . imcontour( x , y ,___) uses the vectors x and y to specify the image x- and y coordinates.

How do you plot the contour of an equation in MATLAB?

fcontour( f ) plots the contour lines of the function z = f(x,y) for constant levels of z over the default interval [-5 5] for x and y . fcontour( f , xyinterval ) plots over the specified interval. To use the same interval for both x and y , specify xyinterval as a two-element vector of the form [min max] .
