 Other toolboxes required dec_to_bin Converts a number to its binary form in a similar way to the de2bi function in MATLAB. none Helper functions
 This is a helper function that only exists to aid other functions in QETLAB. If you are an end-user of QETLAB, you likely will never have a reason to use this function.

dec_to_bin is a function that takes a number as input and converts it to a vector representing the binary form of the number with the MSB to the right.

Syntax

• BIN = dec_to_bin(DEC)

Argument descriptions

• DEC: The number to be converted to a vector representing the binary form of DEC. This must be a non-negative integer.

Examples

Some basic examples of how dec_to_bin works.

```>> dec_to_bin(5)

ans =

1     0     1

>> dec_to_bin(6)

ans =

0     1     1```

Notes

This function is only meant to simplify code within other functions without the need to install the communications package of MATLAB or Octave-Forge.
