Hello everyone, I am kinda new in MatLab and I got a question how to implement this Linear Equation System

[5] = [1 1] [x0]

[10] = [1 2] [v0]

These are my equations and I need to solve it with MatLab. We should use the Y=inv(x) command.

Can anyone help me with these?

I believe this would work if I understand your equations correctly:

x0v0 = inv([1 1; 1 2]) * [5; 10];

Thanks this really helped. If I implement the equations only, I do x0=[1 1]*[5] and v0=[1 2]*[10]

am I right?

My pleasure.

You would implement the equations as:

Out = [1 1; 1 2] * x0v0;

if I understand correctly what you want to do.

Any text on linear algebra (or matrix algebra) will give you all the details on how matrix multiplication works.
