dask.array.linalg.solve_triangular(a, b, lower=False)[source]

Solve the equation a x = b for x, assuming a is a triangular matrix.

a(M, M) array_like

A triangular matrix

b(M,) or (M, N) array_like

Right-hand side matrix in a x = b

lowerbool, optional

Use only data contained in the lower triangle of a. Default is to use upper triangle.

x(M,) or (M, N) array

Solution to the system a x = b. Shape of return matches b.
