Hello! I need some problems with using function varsize. This is my code:
lambda = struct('lower', 0, 'upper', 0, 'eqlin', 0, 'ineqlin', 0);
coder.varsize('lambda.lower', [1,inf]);
coder.varsize('lambda.upper', [1,inf]);
coder.varsize('lambda.eqlin', [1,inf]);
coder.varsize('lambda.ineqlin', [1,inf]);
[xopt,zmin,exitflag,output2,lambda] = linprog(C1,A,B,[],[],LB1,[],[],options);
fprintf(1,Out1,xopt,zmin);
fprintf(1,'ExitFlag= %d\nIterats= %d\n',exitflag,output2.iterations);
fprintf(1,'Algorithm - %s\n',output2.algorithm);
fprintf('Dual problem\n');
fprintf(1,'y1 = %1.5f\ny2 = %1.5f\ny3 = %1.5f\n', lambda.ineqlin(1),lambda.ineqlin(2), lambda.ineqlin(3));
And I see this error:
MATLAB expression 'lambda.lower' is not of the correct size: expected
[1x1] found [3x1].
I try to compile MEX-function with codegen. What's wrong?

My solution.
if isempty(Aeq)
valueAeq = [];
else
valueAeq = ones(size(Aeq,1), 1);
end
if isempty(A)
valueA = [];
else
valueA = ones(size(A,1), 1);
string1 = [ ' ',num2str(A(1,1)),'x1)'];
end
lambda = struct('lower', ones(size(C,2),1), 'upper', ones(size(C,2),1), 'eqlin', valueAeq, 'ineqlin', valueA);
[xopt,zmin,exitflag,output2,lambda] = linprog(C,A,B,Aeq,Beq,LB1,[],[],options);
If someone knows how to do it better, I will be happy to see a solution.
