Matlab help pls, i am new to matlab and would appreciate any help

Can Someone help explain this code below
A(k,i) = m_Data(1,i,k);

this is embedded in two loops

for i=1:N
for k=1:M

yourcodegoeshere

end
end

What it does it take a subset of the m_Data matrix and use it to populate the A matrix. It is inefficient, and should be vectorized.

A(:,:)=(m_Data(1,:,:))'

would live outside the two loops, and could run as much as 12x faster.

this appears to be a function in matlab. k and i are variables that are to be input by the user.

Depending on the function created, they will result in a specific value.

without seeing the actual function code, it is impossible to tell
