Please explain the concept of zeros for images...the code is [m n]=size(image); image1=zeros(8,m,n);

Please explain the coding for the above syntax

Answer 1

[Walter Roberson]

zeros() just returns a matrix the given size, with all of the values in the matrix set to 0. For example, zeros(3,5) would be the same as

[0 0 0 0 0; 0 0 0 0 0; 0 0 0 0 0]

Answer 2

[Azzi Abdelmalek]

image1=zeros(8,5,2)

This line of code allows to pre allocate memory for a matrix 8x5x2, to be used after. you can fill your matrix with other values then zero, and make the process faster

[Gursheen]

sir why has the number 8 been fixed? please specify what does 8,5,2 specify here as in 5,2 must be rows and columns then what does 8 signify?
