could anyone help me how to frame the matlab code with respect to the expression

Values:

i=4,j=2

Expression:

Answer 1

[Walter Roberson]

var(x) * length(x)

unless it is possible for the m of the second equation to be different from the n of the first equation.

It was my mistake i just gave the values of i and j to be 4 and 2.Actually the value of i=[0.6424 0.0101;

0.8241 1.3921;

1.5931 0.8082;

2.7726 1.3897]

and j=[0.5060 0.8909;

0.6991 0.9593]

now i need to make use of the two matrix in the above expressions.

Could you please help me on this.

It does not make sense to use 0.6424 (etc) as subscripts on your vector x

I also do not understand what the meaning is of the heavy black bar to the right of the second expression.
