# Cartesian to polar coordinates c++

So far everything is working fine, until I try to build spherical coordinates from a cartesian vector. Here is the code I am trying right now, but it's not working correctly (changing phi . To Convert from Cartesian to Polar. When we know a point in Cartesian Coordinates (x,y) and we want it in Polar Coordinates (r,θ) we solve a right triangle with two known sides. Example: What is (12,5) in Polar Coordinates? Use Pythagoras Theorem to find the long side (the hypotenuse). I am attempting to convert an image in polar coordinates (axes are angle x radius) to an image in cartesian coordinates (axes are x and y). This is simple enough in matlab using pcolor() but the issue is that I must do this in a mex file (c++ interface to Matlab).

# Cartesian to polar coordinates c++

I am attempting to convert an image in polar coordinates (axes are angle x radius) to an image in cartesian coordinates (axes are x and y). This is simple enough in matlab using pcolor() but the issue is that I must do this in a mex file (c++ interface to Matlab). In the Cartesian system the coordinates are perpendicular to one another with the same unit length on both axes. Cartesian coordinates in the figure below: (2,3) A Polar coordinate system is determined by a fixed point, a origin or pole, and a zero direction or axis. std::polar. template complex polar (const T& rho, const T& theta = 0); Complex from polar components. Returns a complex object (in cartesian format) corresponding to the complex number defined by its polar components rho and theta, where rho .## see the video Cartesian to polar coordinates c++
