Help me. Why this simple Matlab program cannot run?

angelweishan

b=0:0.01:100;
y=atan(sqrt(b+1))-atan(1/sqrt(b+1));
plot(b,y);


Error using  /
Matrix dimensions must agree.

Error in pm (line 2)
y=atan(sqrt(b+1))-atan(1/sqrt(b+1));

第二行的“/”改成“./"试试
b=0:0.01:100;
y=atan(sqrt(b+1))-atan(1./sqrt(b+1));
plot(b,y);
