Can sparse matrix be used in place of zero matrix for space allocation in for loop?

Hi mathworks commnunities,

I developed an optimization model in matlab but i observed the memory allocation of the model is much which slow down the computational time.

My question is if it is possible to use sparse matrix in place of zero matrix for space allocation in for loop statement in order to reduce memory usage?

Part of the code is:

% Wind Generation Constraint

Pwind=zeros(8760,1); % is possible to change to sparse( 8760,1) without altering the duty of for loop?

for ll = 1:nHours

if WindVelocity(ll)<Vci

Pwind(ll)=0;

elseif WindVelocity(ll)>Vco

Pwind(ll)=0;

elseif Vr<WindVelocity(ll)<Vco

Pwind(ll)=20;

elseif Vci<WindVelocity(ll)<Vr

Pwind(ll)=20*((WindVelocity(ll)-Vci)/(Vr-Vci));

end

end

Thanks,

Mic
