Returns a specified row from a matrix.
- a (NxK matrix) – data
- row (scalar) – The row of the matrix to extract
y (1xK row vector) – extracted data
First create a matrix, a:
a = rndn(10, 10);
Now you can assign a variable y to be equal the third row of a with either of the following statements.
y = getRow(a, 3);
y = a[3, .];
While both statements will produce the same result, the first may make for code that is easier to read and interpret.
