Hi I want to decrease the time of calculating in my algorithm. in this algorithm there is an objective function.in every iteration x is achieved from main loop of algorithm then it is entered to objective function in order to calculate the value of objective function. x is a matrix with 1000 rows and 1000 columns and 4 in third dimension. it is (0-1)matrix. also there is the other matrix (c). this matrix has the same rows, columns and third dimension with values between (1-256).this matrix is constant in every iteration.
this is my code:
the function is very simple but why it takes many times to calculate in every iteration.
