Find the units in an expression by using findUnits.

u = symunit;
syms x
units = findUnits(x*u.m + 2*u.N)
units = (N"newton - a physical unit of force."m"meter - a physical unit of length.")
Open Live Script

Find the units in an array of equations or expressions by using findUnits. The findUnits function concatenates all units found in the input to return a row vector of units. findUnits returns only base units.

u = symunit;
array = [2*u.m + 3*u.K, 1*u.N == 1*u.kg/(u.m*u.s^2)];
units = findUnits(array)
units = (K"kelvin - a physical unit of temperature."N"newton - a physical unit of force."kg"kilogram - a physical unit of mass."m"meter - a physical unit of length."s"second - a physical unit of time.")
