Hey every1.. I am working on arrays and I am finding it quite confusing and slowly getting it.. I want to replace the content of a double array with another double array and I belive since is double I should use a nested loop but I am not sure how it works?? I tried several of ways which is below but the content is not being replaced.. I keep checking it from the matlab work space .. My code is below.. the size is 2x100 and in matlab workspace is two rows.. with my code instead of replacing the content it adds extra row to array b?? I want to start the replace from a(3,1) with b(1,1). a(4,1) with b(2,1) etc then when it finishes this row the second row etc

a(x;y)

b(s,f)

d = 2;

for i=3,j=1:100

a(i,j) = b(i -d,j);

i = i+1;

j = j+1

end

Thanks in advance !!

Will this do what you are looking for:

EDIT:

a(:,3:end) = b(:,1:end-2);

OR, if you really wanted a for loop:

d = 2;

for i=1:100-d

a(:,i+2) = b(:,i);

end

eg:

a = randi(15,4,10) % array 4x10

b = randi(20,2,10) %array 2x10

a(3:end,:)=b

And, sorry for mixing up terminology, the "rows" should actually be "columns".
