MATLAB: Loop problem

loop

Hello, I have a loop problem in Matlab

Consider the following datasets:

models = 5×10 (5 rows, 10 columns)

bsdata = 5×20 (5 rows, 20 columns)

I want to do the following calculation:

Result=models(bsdata);

If I do so, I obtain a 5×20 dataset. How can I do this for all the 10 columns of models? I would like to obtain a 10×200 dataset? I have tried the following, but it doesn’t work:

for i=1:10

Result=models(:,i)(bsdata);

end

Thanks,

Pieter

Then:

Result = models(bsdata,:);

You will draw rows direclty fro models.

Hi Rachel Ramirez,

It is my understanding that you want

To check how many times a number repeats in a particular row or column.
Delete that row or coumn if the count is less than 4.

A=randi(5, 10 ,10); % generating a random matrix with dimension 10X10
j=1;
for i= 1:10 
    count=sum(A(j,:)==5); % counting number of times 5 is repeting in jth row
    if(count<4)
        A(j,:)=[]; % deleting jth row if count is less than 4
        j=j-1;
    end
    j=j+1;
end

Hope this helps.
