Abstract: A method, computer system, and computer program product of performing a matrix convolution on a multidimensional input matrix for obtaining a multidimensional output matrix. The matrix convolution may include a set of dot product operations for obtaining all elements of the output matrix. Each dot product operation of the set of dot product operations may include an input submatrix of the input matrix and at least one convolution matrix. The method may include providing a memristive crossbar array configured to perform a vector matrix multiplication. A subset of the set of dot product operations may be computed by storing the convolution matrices of the subset of dot product operations in the crossbar array and inputting to the crossbar array one input vector comprising all distinct elements of the input submatrices of the subset.
