Define a function named tokens_to_str_code that accepts à matrix and a scalar value representing a time_unit. The token matrix has 2 columns and multiple rows. Each row a dot, dash, a short space, a long space or a long-long space. This function uses the rules in the table below to map the token information for one row to either a dot, a dash, or a blank space. You can use these tests to debug your function in MATLAB or Octave: Token Matrix String Code Column One Column Two Converts to: (Token Value) (Token Duration) 1 greater than 4 * time_unit - (dash) greater than or equal to time_unit 1 (dot) but less or equal to 4* time_unit

Transcribed Image Text:Define a function named tokens_to_str_code that accepts a matrix and a scalar value representing a time_unit. The token matrix has 2 columns and multiple rows. Each row represents either
a dot, dash, a short space, a long space or a long-long space. This function uses the rules in the table below to map the token information for one row to either a dot, a dash, a forward slash
or a blank space.
You can use these tests to debug your function in MATLAB or Octave:
Token Matrix
String Code
Column One
Column Two
Converts to:
(Token Value)
(Token Duration)
1
greater than 4 * time_unit
- (dash)
greater than or equal to time_unit
1
(dot)
but less or equal to 4 * time_unit
greater than or equal to 8 * time_unit
(space between a word)
greater than or equal to 4 * time_unit
space (space between characters)
but less than or equal to 8* time_unit
everything else can be ignored – doesn't represent anything
