Monte carlo simulations- vary one parameter at a time or all of them at once?

(may not be a right MATLAB question but more of a theoretical one)

When you do a Monte-Carlo simulation with several fluctuating input parameters, do you vary all inputs separately or at once?

So if I want to vary 10 parameters in my model and let's say for all the individual parameters, I have 100 different values. So shall I perform 100*10 simulations or 100 simulations for one parameter and then for the next one and so on? Maybe I am unclear about the aim of the monte carlo simulations here.

Thanks :)

All parameters are varied simultaneously according to their underlying statistical distribution.

Is there any source/literature that I can refer to? Can I get a link here if possible? :)
