Refer the subset of a matrix, MATLAB in Mathematics

Assignment Help:

Refer the subset of a matrix:

It is also possible to refer to the subset of a matrix. For illustration, this refers to the first & second rows, second & third columns:

>> mat(1:2,2:3)

ans =

3 4

4 5

 

Using a colon for the row index means that all rows, regardless of how many, and using a colon for the column index means that all columns. For illustration, this refers to the whole first row:

>> mat(1,:)

ans =

2  3  4

and this refers to the whole second column:

>> mat(:, 2)

ans =

3

4
