Import Data from an Excel Spreadsheet, sum the data for one column
显示 更早的评论
Use importdata() to import the population data of each country from the data file called World Population.xlsx.
Calculate the total population of each year for each of the six major areas. - I am not sure what to use for this? sumof? sum?
This is what I've written so far.
%% Import population data
filename = 'World Population.xlsx';
[A]=importdata(filename)

I think possible solution will depends on data structure in your Excel file. If possible, could you upload your file?

In order to get the sum of an array, You can use the "sum" function that I have linked below.

If you are trying to get a subset of the actual original array, you'll have to index into the array to select the data before performing the sum. A good resource for array indexing is the following link:
