Your rather confusing question PROBABLY implies you want to plot points that are equally distributed on the surface of a unit sphere, but only in the first quadrant in R^3. In fact, the phrase equally distributed is mathematically meaningless. So I can only presume that you meant uniformly distributed.
The trivial solution is just
X = abs(randn(1000,3));
X = X./sqrt(sum(X.^2,2));
Each row of X is one point. Plot as:
plot3(X(:,1),X(:,2),X(:,3),'.')
box on
grid on
This is my best guess as to what you wanted to do.
Note that it will fail if your MATLAB release is older than R2016b. You can fix that using baxfun in the second line.
