[Gretl-devel] printf: ignore nan values in a matrix

Hi Gretl community, I am wondering whether there is a way to ignore printing NA values in a matrix when calling the printf command Suppose you have a matrix like this: Model=1 Model=2 Model=3 Model=4 INT nan -0.12 -0.17 -0.06 pv nan 0.00 0.00 0.09 U -0.07 -0.09 -0.11 nan pv 0.00 0.00 0.00 nan intercept -176.03 -108.49 6.37 -203.84 pv 0.00 0.00 0.00 0.00 l_INC 6.79 4.28 nan 7.81 pv 0.00 0.00 nan 0.00 trend -0.01 -0.01 -0.01 -0.01 pv 0.00 0.00 0.00 0.00 but you would like to replace all nan values by "" (empty string or no value) for better readability. This should not be the default, but maybe there exists some format argument of which I am not aware of. Thanks Artur
