Generating Samples at Points used in pgfplots












0















For one of my academic courses, i need to generate sample lattices and was wondering if there was any way to generalize the hard-coded points I am using. Instead of repeating -5.19,-3.46,-1.73,0,1.73,3.46,5.19 all the time, is there a way to define a macro or equivalent.
