turning the loop answer into a vector

load data_matrix.mat
data=SECTION_L;
data(:,1:3)=[];
row=9;
cleanup=data([1 2 3 row],:);

for i = 1975:2016
    for j=1:12
        averageM={mean(cleanup(4,cleanup(1,:)==i & cleanup(2,:)==j))}
    end 
end

This script gives me constant 1x1 arrays. This script takes temperatures from each day from each month from each year from 1975 to 2016. The script gives the averages from each month but doesnt put it in a vector, but makes multiple 1x1 arrays and i do not know how to put all the averages into one big vector.

load data_matrix.mat
data=SECTION_L;
data(:,1:3)=[];
row=9;
cleanup=data([1 2 3 row],:);
c=1;
for i = 1975:2016
    for j=1:12
        averageM(c)={mean(cleanup(4,cleanup(1,:)==i & cleanup(2,:)==j))};%index into averageM
        c=c+1;
    end 
end

Conversion to double from cell is not possible.

Error in untitled6 (line 9)

averageM(c)={mean(cleanup(4,cleanup(1,:)==i & cleanup(2,:)==j))};%index into averageM

it is giving me this an error when i run the script

[Walter Roberson]

We do not know what class(SECTION_L) is. Also, it is possible that you had an existing numeric averageM in your workspace that is interfering with the assignment.

I changed the name of the numeric and it worked. Thank you, both of you.
