so let say I have two files fileA.m & fileB.m in fileA.m I have this code
dataX = 100;
in fileB.m I want to use if to check the value this is what I have in fileB.m
if dataX == 100
fprintf('Value is %f \n' , dataX);
fprintf('Value is NOT %f \n' , dataX);
however I'm having problem every time I run fileB.m I get this error Undefined function or variable 'dataX'.
so how can I access global variable from another .m file .. I'm new to Matlab
