[求助]
想把m文件在simulink 中的调用，我用的是matlab function 模块。
|
|
RT 我的m文件的代码是function h_vs= fcn(T_s) B13= [-575.520*10^-4 117.700*10^-5 491.369*10^-8 782.701*10^-2 -815.233*10^-3 256.383*10^-4 149.856*10^-1 -209.283*10^-2]; a=zeros(1,8); for i=1:8 a(i)=B13(i); end coder.extrinsic('syms'); syms h_vs u v; T_s=T_s+273.15-61; v=T_s-203.15; u=(h_vs-350)^0.5-2.24076; x=solve(u^3+a(1)*u^2*v+a(2)*u*v^2+a(3)*v^3+a(4)*u^2+a(5)*u*v+a(6)*v^2+a(7)*u+a(8)*v,h_vs); y=max (real (double (subs(x)))); h_vs=y; end 复制到matlab function中想要调用却出现如下8个错误： Simulink does not have enough information to determine output sizes for this block. If you think the errors below are inaccurate, try specifying types for the block inputs and/or sizes for the block outputs.
