Angle Approximations of a Grid

Subject: Angle Approximations of a Grid

I have a matrix of grid values corresponding to a coordinate system of a square shape. Each grid point/matrix entry corresponds to an x and y position where a measurement was taken with respect to time. Therefore each position has a corresponding time series. I want to be able to obtain only the values lying on a line drawn from one corner forming an angle (10,20,30,...90) so that I can perform an fft with the corresponding time series data. Any suggestions on how to isolate these data points?
