If I understand correctly, you are trying to link the mat library,

Because you need invoke option l in the following form:

gcc test.cpp  -o test.exe -lm

i.e, you omit the 'lib' prefix, and the part '.a' of the name of
library.

This info appears in the FAQ. See question 8.8 'Undefined
references when linking programs'
