Algebra Problem help

Hi,

I have matrix A of [ I/100 + 0.1 I/100 + 0.2 I/100 + 0.3 I/100 + 0.4
I/100 + 0.7 I/100 + 0.8 I/100 + 0.9 I/100 + 1.1 ]

+
[2 0
0 2
0 0
0 0
0 0
0 0]


I tried A = [I\100 + 0.1 I\100 + 0.2 I\100 + 0.3 I\100 +0.4 ; I\100 + 0.7 I\100 + 0.8 I\100 + 0.9 I\100 + 1.0] + [ 2 0 ; 0 2; 0 0; 0 0; 0 0; 0 0]


And there is this error:
??? Capitalized internal function I; Caps Lock may be on.
So how should i write this part? please advise. Thanks.

What application are you using to calculate?

Is this an addition of matrices? If so, they have to be the same dimensions. What does the 'I' signify? Is it just a variable for which you're trying to solve, or does it represent an imaginary number?

if this is matlab, and you mean i = sqrt(-1), you need to use a lower case i (or j).

Hi,

Here's the attached question.
Here's my try:

A = [I/100+0.1; I/100+0.2; I/100+0.3; I/100+0.4; I/100+0.5; I/100+0.6; I/100+0.7; I/100+0.8; I/100+0.9; I/100+1.0; I/100+1.1; I/100+1.2; I/100+1.3; I/100+1.4; I/100+1.5; I/100+1.6; I/100+1.7; I/100+1.8; I/100+1.9; I/100+2.0; I/100+2.1; I/100+2.2; I/100+2.3; I/100+2.4; I/100+2.5; I/100+2.6; I/100+2.7; I/100+2.8; I/100+2.9; I/100+3.0; I/100+3.1; I/100+3.2; I/100+3.3; I/100+3.4; I/100+3.5; I/100+3.6] + [2 0 0 0 0 0; 0 2 0 0 0 0; 0 0 2 0 0 0; 0 0 0 2 0 0;0 0 0 0 2 0; 0 0 0 0 0 2]

And here's the error:
??? Capitalized internal function I; Caps Lock may be on.

In this case, I is undefined. So what should i input to make this program works? Please advise. Thanks

use lowercase i. I = sqrt(-1). In matlab, i = j = sqrt(-1).
