I'm a student currently working on a MatLab project that requires me to use xlsread to read an xls file that contains a random number of students (rows) and 16 columns (grades of homework/projects/exams/etc) and I am required analyze each students' data (one by one), keep track of each total, and ignore the data that doesn't exist using isnan. The problem is I don't know how I can use isnan and ignore the values that don't exist without changing the values that are 1 to 0. Also, we aren't allowed to use the nansum/nanprod functions either. If this doesn't make much sense, my professor provided an algorithm pseudocode which makes more sense than what I posted up there.
Here it is:
[code]% Import Data into MatLab
% type in help xlsread to see how to use this function
% you will need to know how many times you want to repeat the analysis
% run a loop, on each iteration, analyze the data of a SINGLE student
% keep track of the totals for each group of assignment (i.e. PSs, PROJs,...)
% When adding up items, make sure you neglect those that are NaN - find
% them and don't use them - use isnan[/code]
