Hello All,
Here is the small function i want to convert to C using Matlab coder.
function []=fun()
x=ones(9,11).*[0:10:100];
var1 = 0;
for t=11:500
a1=(rand-0.5)*1;
x(1,t+1)=x(1,t)+a1;
if x(1,t+1)<(100-var1) || x(1,t+1)>(100+var1)
x(1,t+1)=x(1,t);
end
end
end
I am getting size mismatch error: [9,11] ~=[1,11] in Matlab coder.
Things I tried
function []=fun()
x=bsxfun(@times, ones(9,11),[0:10:100]); % Changed this line
var1 = 0;
for t=11:500
a1=(rand-0.5)*1;
x(1,t+1)=x(1,t)+a1; % error in this line
if x(1,t+1)<(100-var1) || x(1,t+1)>(100+var1)
x(1,t+1)=x(1,t);
end
if sum(x(:,t+1))/9<100-5
x(:,t+1)=x(:,t+1)+5;
end
end
end
Error : Index exceeds array dimensions. Index value 12 exceeds valid range [1-11] of array x.
function []=fun()
x=bsxfun(@times, ones(9,11),[0:10:100]);
x=repmat(x,[1,1290]) % Changed this line
var1 = 0;
for t=11:1290
a1=(rand-0.5)*1;
x(1,t+1)=x(1,t)+a1;
if x(1,t+1)<(100-var1) || x(1,t+1)>(100+var1)
x(1,t+1)=x(1,t);
end
if sum(x(:,t+1))/9<100-5 % error in this line
x(:,t+1)=x(:,t+1)+5;
end
end
end
Error: Sizes mismatch: [1290][9] ~= [14179][9]. in coder and also it is not correct because in my main file dimension of x and other variable is not matching. So I think it is better not to use repmat.
Please give your suggestions. I will try to apply in my code.
Thank You
Manoj

I'm not all that familiar with the coder, but look at/read the documentation thoroughly first...
<Coder controlling-memory-allocation> looks like a good starting point.
