Undefined function and type 'double"...anyone can help?

% Locate the operating point of PV module and

% calculate its voltage, current, and power

f = @(x) x - Rin*bp_sx150s(x,G,TaC);

Va_k = fzero (f, [0, 45]);

Ia_k = bp_sx150s(Va_k,G,TaC);

Pa_k = Va_k * Ia_k;

error:

Undefined function or variable 'Va'

Undefined function or variable 'f'.

What question do you have about this error? It looks like you will have to find an alternative to using this anonymous function if you want to use code generation.

Also, your title doens't match your code or your error, so editing it to an appropriate title might help you getting a meaningful answer.
