Some useful ROOT Macros

Random numbers following an exponential (using inversion method): random_1.C.html
Simple histogram fit with TF1: fit_with_error_matrix_1.C.html
Fit data points with TF1: fit_with_error_matrix.C.html
Contour plot example (from ROOT tutorials): fitcont_root_tutorial.C.html
Another example of fitting data points, including an incorrect error band (but the example shoudl be useful): fit_with_error_matrix_eg.C.html

The simple macros above can be executed with:

> root 
>> gStyle initialized
root [0] .x random_1.C

Note: if macro filename (say, filename.C) and the function name in the macro are different (say void function()), then the way to execute the function is:

root [0] .L filename.C
root [0] function()

Note that to run the examples above one has to remove the ".html" at the end of the filename.
