Solves the linear equation set a * x = b for the unknown x for square a matrix. If the data matrix is known to be a particular type then supplying the corresponding string to assume_a key chooses the dedicated solver. The available options are If omitted, 'gen' is the default structure.

x = np.linalg.solve(A, b) print(x) This gives the following solution: [[-4. ] [ 4.5]] This means: ! "=−4! %=4.5 Which is the same as the solutions we got from the other methods x = np.linalg.solve(A, b) We can also use the linalg.solve()function Note! The A matrix must be square and of full-rank, i.e. the inverse matrix needs to exists.

Sweeping a Parameter. If you have a system where the coefficients change as a function of some parameter, you will generally need to use a loop to solve and store the solutions. numpy.linalg.solve() function .

x = np.linalg.solve(A,b) Application: multiple linear regression. In a multiple regression problem we seek a function that can map input data points to outcome values. Each data point is a feature vector (x 1, x 2, …, x m) composed of two or more data values that capture various features of the input.
