    can someone check my circuit?it can't work, thanks

    Hi, I think that your problem is due to the high number of parallel resistances and their low values. You have ten resistances of 82Ω+130Ω =212 Ω in parallel. If possible try to increse these values to 820+1k3 or 8k2 + 13k, for example.

    Simulink Matlab Function Block Question

    simulink function block Hi, You could use a mux block to group several signals in the same line. But in your case it's not possible becase one input is a matrix and the dimension of the signals to be grouped would be different. Maybe the best solution is to create a S-Function, but it is more...

    Vector quadratic equation

    I think the answer is no, because you have only one equation to solve N unknowns, and therefore you will have infinite solutions.
