I have no clue what this means? Given the following matrix, what is the value of a11? [8 11 13] [17 0 6] [4 16 18]
r1, c1 is the entry in the first row first column
so it would be 11x8 ?
no, a11 is the number in row1 and column 1. in this case = 8. If it was a12 it would be 11...
a11 would be the entry in the 1st row 1st column: 8 is it
Oh, ok i see the way you wrote the first thing made me think you had to multiply them, thank you very much
the name of the matrix is a it has r, rows and c, columns a_rc defines which row and which column
