Whitespace after characters

IDLAYOUT-4
TitleCommas, semicolons and keywords shall be followed by a space unless at the end of the statement.
PriorityStrongly recommended
DescriptionCommas, semicolons and keywords (for, while, if etc.) shall be followed by a space unless at the end of the statement. A clear separation of keywords from other code improves readability.
RationaleReadability

Avoid:

while(ismember(x, [3,5,7,11,13]))
    x = x + 2;
end

Instead use:

while ismember(x, [3, 5, 7, 11, 13])
    x = x + 2;
end
