CSV Read Issues and Structural Arrays-Help me debug the CSV portion

Basically, I have a csv file with data about test results (the first row is a

header) and it has two columns. I have to find the mean, stdev, max and min of

the two columns separately, as fields in a structure array. I know how to find

the statistics, but I'm having trouble making the csvread function work and

making it a structure array. Here's what I have thus far to try to read the

file:

    % 
function S= E7stats(filename)
filename='grades_E7MT1.csv';
S=csvread(filename,1,0);
