First graph is in real domain, second graph is in convolution domain by convolution transform convolute(x) with x
Input your function, click the convolute button. e.g.
put your function f(x,y) into sin(f(x,y)) by contour transform sin(z). First graph is in real domain, second graph is in contour domain.
Input your function, click the plot button. e.g.
sin(x*x+y*y-1)
Input your function, click the plot2D button. e.g.
First graph is real function, second graph is complex function, where blue line is real part re(z) and red line is imag part im(z) by convert to complex with tocomplex(x)
Input your function, click the complex2D button. e.g.
