i add the value of c in string and than sendas visa command but it is not working i use two types of code below
c=1;
for i=0:10
c= 0.2+c;
u=fprintf('SOUR:VOLT %dV, (@2)',c);
fprintf(obj, 'u ');
end
also the in second try i use concatenation of string like given below
for i=1:4
%c= i+c;
s2 = 'SOUR:VOLT' ;
s1 = num2str(c);
s3 = 'V, (@2)';
s = strcat(s2,{' '},s1,s3);
fprintf(obj, 's' );
end

You have
u=fprintf('SOUR:VOLT %dV, (@2)',c);
you are trying to use an integer format, %d, for a non-integer value, which is changing by 0.1 at a time. You should use
u=fprintf('SOUR:VOLT %.1fV, (@2)',c);
