Hi,

I want to create a string of dots character like the function blanks does to create spaces. how do I do that?

Use repmat:

repmat('.', 1, 10)

Answer 2

[David Sanchez]

function my_dots(n)
str = '';
for k=1:n
    str = strcat(str,'.');
end
disp(str)

>> my_dots(3)

...

>> my_dots(10)

..........

In every iteration, str grows by one element, making this painstakingly slow with increasing n … MLint warns you for this problem.
