Why the following code gives error?
lb=[0 0 0 0]; ub=[10 10 pi pi]; nPop=30; D=4;
Error using unifrnd

This cannot be done in single call to unifrnd. You need a for-loop
lb = [0 0 0 0]; ub=[10 10 pi pi]; nPop=30;
D = numel(lb);
M = rand(nPop, D);
for i = 1:D
M(:,i) = unifrnd(lb(i),ub(i),[nPop,1]);

Further, when i rant it with my own old fitness function (before your chnages), again it gave error as:
Subscripted assignment dimension mismatch.
Error in fun2sn0 (line 13)
[~, ix1(ix)] = sort(b); % temp stores the randomly generated vector "best" by algorithm
Error in GQPSO (line 54)
f_x(i) = feval(fun,x(i, :));
Error in myfit_driver (line 2)
[xmin,fmin,histout] = GQPSO(@fun2sn0,4,30,[0 0 0 0],[10 10 pi pi],2000,10000*4);
