indexing, How to index into a cell with vector contining zeros/ Nan

Hello,

How to index into a cell with vector contining zeros/ Nan? %Array indices must be positive integers or logical values.

How can i find data for the same country that have two differnt names? like USA and united states

for the attached data, i need to calculate:

percent_pv = IRENA_world_solar * 100 / UN_Total_MW; for each same country in the same year.

percent_wind = IRENA_world_wind * 100 / UN_Total_MW; for each same country in the same year.

[A, Locb]= ismember (IRENA_countries, UN_Total_MW_countries)       %nnz(A)
[Ar, ia] = setdiff(IRENA_countries, UN_Total_MW_countries)
UN_Total_MW2 = UN_Total_MW_countries(Locb)

Thanks for the help! or any Hint.
