What is wrong with this array

function countValues = CreateArray(endValue)
% endValue: Ending value of array countValues

      % Construct a row array countValues from 1 to endValue, 
      % using the double colon operator
      countValues1 = [1:5]
      countValues2 = [1:8]
  end

[per isakson]

• countValues, countValues1 and countValues2 are three different variables.
• The input argument, endValue, is not used
• Why 5 and 8 ?
• Homework, I assume. The code in your question, is it a template provided by your teacher?

[Walter Roberson]

What is the "double colon operator" ? Is that the general form for the colon operator, A : B : C ?

Answer 1

The instruction is clear:

Construct a row array countValues from 1 to endValue

But you create two arrays called countValues1 and countValues2, which are going from 1 to 5 or to 8, respectively. Construct one array, which is called "countValues" and goes from 1 to endValue. Now all you have to do is to translate "to" to the colon operator and insert a "=".

You do not need the square brackets, because they are the operator for a concatenation. But 1:5 is a vector already and no concatenation is needed.
