what's the answer and what's mean ?? about matrices

a = [ 3 4 ; 5 6 ]

b = [ 1 0 ; 0 1 ]

g = a|b ------> what's the answer and what's mean ??

Answer 1

[Amjad Green]

g=[1 1;1 1]

mean of matrix is the sum of each column divied by number of elements in it

so in this case mean of matrix is a 1*2 matrix

[ahmad qadan]

thank you ,, but can you explain me how the sum column process was done

You are asking for the meaning of the operator | , not for the mean() of a matrix.

a = [ 3 4 ; 5 6 ]
b = [ 1 0 ; 0 1 ]
g = a|b

The result is:

g = [1,1; ...
     1,1]

and the operator | is the same as or(): Reply 1, if either the element of a or the element of b is not 0.
