NumPy Matrix Multiplication - np.matmul() and @ [Ultimate Guide] - Be on the Right Side of Change

NumPy’s np.matmul() and the @ operator perform matrix multiplication. They compute the dot product of two arrays. For 2D arrays, it’s equivalent to matrix multiplication, while for higher dimensions, it’s a sum product over the last axis of the first array and the second-to-last of the second array. Have you ever tried to multiply two ...

1) Find the coefficients using the Linear Least Squares model:Write a function `designmatrix` which takes as input a numpy array with shape (n,) that stores the values for t, and outputs the design matrix A, which leads to aleast-squares fit to the equation above.def designmatrix(t):#t is a 1d numpy array with shape (n,) storing [t0, t1, t2, ...]# compute A, a 2d numpy array, following the model abovereturn A
