Request to assist:-

I have matrix A=[1,0,3; 0,5,6; 7,8,9] and

I expect output:- x1 = 3; x5 = 6; x7 + x8 = 9;

without any single quote or double quote to variable.

Is there any way to get it?

Answer 1

[KSSV]

A=[1,0,3; 0,5,6; 7,8,9] ;
iwant = A(1,3)+A(2,3)

Thanks for your time.

But, I have a matrix

A=[1,0,3; 0,5,6; 7,8,9] ;

and I want output in the form of three equations:

x1 = 3

x5 = 6

x7 + x8 = 9

[KSSV]

are you looking for:

syms x1, x5, x7, x8 
x1 == 3 ;
x5 == 6 ;
x7+x8 == 9 ;

[Kushal Jagtap]

Yes, I just want three equations you mentioned.

Answer 2

Without any other guidance, like how the various x are related to the A, here is one way that will work:

function [x1,x5,x7,x8] = YourFunction()
x1 = -3;
x5 = 6;
x7  = 2; % Whatever you want.
x8 = 9 - x7;
