division of two 200 by 1 matricies produces: Error using * Inner matrix dimensions must agree

I have two variables: GtCCO2Diffh and CO2emithc.

size(GtCCO2Diffh) returns [200 1] --> a 200 row x 1 col matrix

size(CO2emithc) returns [200 1] --> a 200 row x 1 col matrix

but when I go to divide (or multiply) the two variables, I get "Error using * Inner matrix dimensions must agree.

Note GtCCO2Diffh is calculated using the following steps:

CO2h = ncread('spatially_int_Historical.nc','A_co2');
GtCCO2h =CO2h*2.123;
GtCCO2Diffh = GtCCO2h - GtCCO2h(1)

While CO2emithc is calculated in the following manner:

CO2emith = ncread('spatially_int_Historical.nc','F_co2emit');
CO2emithe = CO2emith*((365*24*60*60)/1E12);
CO2emithc = cumsum(CO2emithe);

My goal is to divide the two matricies to produce a new matrix representing the fractional value of the remaining Atmospheric Carbon (GtCCO2Diffh) over the CO2 emissions emitted(CO2emithc)

Why might this be?

Thanks!

How did you divide?

out=A./B % instead of A/B
out=A.*B   % instead of A*B
