I create a matrix of size 3x3 called mat_1 and then I want to iterate over all the values one by one and print the element as well as the position in the matrix:
My code is : mat_1= matrix( c('1','2','3','4','5','6','7','8','9'), nrow = 3, ncol = 3,byrow = TRUE) mat_1 # Loop over my_matrix for(row in 1:nrow(mat_1)) { for(col in 1:ncol(mat_1)) { print(mat_1[row, col]) } } But I don't know how to print elements and positions as well of this matrix?
