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.

UN_Total_MW2 = UN_Total_MW_countries(Locb(A))
