ROWBITS

Purpose:

Sums each row of a table as bit values.

Syntax:

ROWBITS(a)

a

-

A multi-column series of ones and zeros.

Returns:

A single column series of the same length as the input. Each value of the series is the bit sum of the input rows.

Example:

W1: {{0, 0, 0, 0},

     {0, 0, 0, 1},

     {0, 0, 1, 0},

     {0, 0, 1, 1},

     {1, 1, 0, 0}}

 

W2: rowbits(w1)

 

 

W1 contains a 5x4 table of values where each value is a 1 or a 0. Each row is considered a 4 bit binary value where the MSB is the first column.

 

W2 contains the series {0, 1, 2, 3, 12}, the bit values of each row of W1.

Example:

W1: int(rand(3, 10) * 100) > 50

W2: rowbits(w1)

 

W1 contains a random 3x10 table of values where each value is a 1 or a 0. Each row is considered a 10 bit binary value where the MSB is the first column.

 

W2 contains the series of bit values of each row of W1.

Remarks:

ROWBITS assumes each row contains bit value of 1 or 0 where the first column is the MSB.

 

Any number of columns can be processed, each row of an N column series represents an N bit value.
