While running this file I m getting an error as ??? Improper assignment with rectangular empty matrix. I dont know what wrong I m doing? va is vector and d_va may have some nan value also.
b=floor(100-100*min(sp)); d_va=zeros(1,b);
for a=1:b
m=(100-a)/100;
xa=find(m-0.001 <= sp & sp <= m+0.001, 1, 'last' );
m2=m-(0.05*m/100);
xb =find(m2-0.001<=sp & sp<=m2+0.001, 1, 'last' );
va1=va(xa);
va2=va(xb);
d_va(a)=(va1-va2)*100/va1; % This line shows an error,??? Improper assignment with rectangular empty matrix.
end
end

It is easier to diagnose your code if you provide a complete working example (with values for the variables b, sp, etc.)

I can't reproduce your exact error message, but it is probably occurring because either va or vb are empty (there weren't any values of sp in the correct range). What you do depends on whether this is an error or it is o.k. If the latter, you could try something like this:
dva = zeros(b,1); % You should initialize dva
...
if any(va1) & val~=0 & any(va2)
dva(a)=(va1-va2)*100/va1;
end

you mentioned 'dv(a)', whereas in the code it is 'dva(a)'- have you got variables called 'dv' and 'dva' ?
