Attempted to access solutionsofar(:,0); index must be a positive integer or logical.

function run_cont(fun,N)

global solutionsofar functionname

functionname=fun;

for k=1:N

ig=2*solutionsofar(:,end)-solutionsofar(:,end-1);

x=newton('continuationloop',ig);

solutionsofar=[solutionsofar,x];

end

This gives me error

Attempted to access solutionsofar(:,0); index must be a positive integer or logical.

Error in run_cont (line 8)

ig=2*solutionsofar(:,end)-solutionsofar(:,end-1);

Please suggest me a fix. Thank You

You have to assign something into solutionsofar, apparently it has 0 element.
