Actually, it is the exact opposite of Cartesian indexing.įor the matrix shown above, for a given row Y-coordinate increases as 0, 1, 2, 3 from left to right whereas for a given column X-coordinate increases from top to bottom as 0, 1, 2. Consider the above figure with X-axis ranging from -4 to 4 and Y-axis ranging from -5 to 5. Meshgrid function is somewhat inspired from MATLAB. The indexing of Matrix is however different. The shgrid function is used to create a rectangular grid out of two given one-dimensional arrays representing the Cartesian indexing or Matrix indexing. The shape of x_1 changed from (11, 9) to (1, 9) and that of y_1 changed from (11, 9) to (11, 1) X_1, y_1 = np.meshgrid(x, y, sparse = True) One row of x_1 and one column of y_1 is enough to determine the positions of all the points as the other values will get repeated over and over. We observe that x_1 is a row repeated matrix whereas y_1 is a column repeated matrix. The way a plane passes through a tet (if.
