MATLAB: Plot x=f(y)

MATLAB C/C++ Graphics Libraryplotting

If I have a function given as x =f(y), how can I plot x as independent variable (x axsis) and y dependent variable (y axsis). I also need to control the range of both x and y.

x=y/(0.5+cos3y)

In MATLAB, cos3y would be written as cos(3*y)

In MATLAB, if y is a vector, instead of using / you should use ./ -- so y./something instead of y/something

You have an implicit plot, so you should have a look at fimplicit()

See if this does what you want:

y = ...;                                    % Choose A Vector
fy = f(1,y);
figure
plot(y, fy)

Depending upon how you define the fuction and how you want to plot it, you may need:

x = ones(size(y));

instead of the scalar value of 1.

Then the plot call would be:

figure
plot(y,f(x,y))

figure
surf(x,y,f(x,y))

Depending on how you wrote the function.

Hi, you could try the below code

fimplicit(@(x,y) x);hold on;fimplicit(@(x,y) y)
