Speeding up Matlab-Simulink Running in a Loop

Hi I have fairly large Simulink Model (however it runs fast). Now Am running the model from Matlab using SIM command and Nested For Loops, where I change variables in Simulink Model at every step.

is there anyway to speed up the simulation ?? Currently it takes 10 minutes for 780 simulations, however I want it to be more efficient.

The code am using is as following:

 clear
clc
close all
X=10:15:210;    % Variable 1 to be changed every run
Y=4.5:-0.15:3;  % Variable 2 to be changed every run
for q=1:length(Y)
rini=Y(q);                  % Variable in Simulink Model
for i=1:length(X)
    T_l=X(i);                % Variable in Simulink
    sim('Vaildated_sen.slx')
%%Post Processing Simulink Results %%%
    vec1(i,:)=T1./T22;         % T1,T22 are outputs From Simulink Model
    vec2(i,:)=(F2./F1);        % T1,T22 are outputs From Simulink Model
    vec3(i)=T_l/100;           % T1,T22 are outputs From Simulink Model
    vec4(i,:)=r1;              % T1,T22 are outputs From Simulink Model
    vec5(i,:)=r1d;             % T1,T22 are outputs From Simulink Model 
    A=vec4(i,:);
    indices(i,:) = find([0 diff(sign(A))]~=0); %%Find the index of a point
    d=indices(:,2);
    FR_temp=vec1(:,d);
    GR_temp=vec2(:,d);
%Storing Post Processed Results
    TR(i)=ku(i)/t_in;
    FR(q,i)=FR_temp(i);
    RR(q,i)=GR_temp(i);
    GG(q,i)=rini2(q)/3;
%%%Clear and start new X
clear vec1 vec2 vec3 vec4 vec5
end
end

Thank you
