F.mat

Hello, I am trying to run a simple simulink model but i would like to automate the input from a m.file. It should run 201 times since there are 201 columns of time-input and report the output into a matrix. Is there any way to do this? thank you

load F.mat % attached 
p=1:201 % number of columns 
Force=zeros(512,201)
for n=1:p
   Force=F(:,p) 
     sim('test') % below
end

load F.mat % attached
% a matrix of F is loaded, it is a 512x201 double array
p=size(F,2) % number of columns
for n=1:2 % for testing first, change it to be "for n=1:p" later
   Force=F(:,n) 
     sim('test') % below
end

Not like that. p would be 202 because SimT has 202 columns.

load F.mat % % a matrix of F is loaded, it is a 512x201 double array
p=size(F,2) % number of columns
Tin=linspace(0,30,p)'; % time steps 30 seconds 
Results=cell(1,p);
for n=1:3 % for testing first, change it to be "for n=1:p" later
     Force=[Tin F(:,n)] 
     Results{n}=sim('test',Tin) % below
end

Thank you

I got the code to work. This is final code.

load F.mat % % a matrix of F is loaded, it is a 512x100 double array
p=size(F,2) % number of columns
Tin=linspace(0,30,512)'; % time steps 30 seconds 
Results=cell(1,p);
for n=1:p % for testing first, change it to be "for n=1:p" later
     Force=[Tin F(:,n)] 
     Results{n}=sim('test',Tin) % below
end
