MATLAB

What does this sentence in matlab? kvalue=zeros(size(data,1));

data word is a database.

Best Answer

Example

data=[1 2 3;4 5 6]
n=size(data,1) %  is number of rows of data
size(data,2) % is number of columns of data
zeros(n)     %will create a nxn array of zeros

MATLAB: Kvalue=zeros(size(data,1),size(data,1),size(data,2));

 kvalue=zeros(size(data,1),size(data,1),size(data,2));

The above line is just initializing an array of zeros that has dimensions MxMxN where M is the number of rows in data and N is the number of columns.

So that,

data = randn(8,4);
kvalue=zeros(size(data,1),size(data,1),size(data,2));

kvalue is a matrix of zeros that is 8x8x4. The matrix of zeros is then filled with values in the following for loop.
