polynomials summation equation solving
显示 更早的评论
Hi There, I want to write a code to solve the following two polynomials to write them in Simulink block]
I have 39 values of Cn, S, t, u, v for the first polynomial and 47 values for the same variable for the second polynomial. Many Thanks in advance.

You cannot use a Polynomial block for those because those are not polynomials. Polynomials do not raise values to powers that are variables.
I think you will need to use a MATLAB Function Block.

K = sum( C .* J.^S .* (P./D).^t .* (AE./A0).^u .* z.^v );
And use this same function twice with the different sets of inputs, since the formula is the same for both cases.

You would not need a "for" loop to do it. I coded as a vectorized expression that should be fine as long as all of the elements are either scalar or the same length. If some of the arrays might be longer you can index them at the length you want. For example,
N = 37;
K = sum( C(1:N) .* J.^S(1:N) .* (P./D).^t(1:N) .* (AE./A0).^u(1:N) .* z.^v(1:N) );
