How can I remove the extra blank spaces from a text?

For example, I have the sentence ' I will go to the cinema' . I need this sentence to be written as 'I will go to the cinema'. I need to delete the extras spaces.

@Tiziano dos Santos - you could perhaps use strsplit to split the string on the space character and will create a cell array of strings (the words from your sentence). You could then use join to combine the words with a space between each one (may also need to trim the string first).

There is also probably a clever (better way to do this using) regexprep command that will do the same thing. I tried it and it wasn't too difficult to do.

How did you do it with regexprep?

[Walter Roberson]

S = '   I will  go to           the   cinema' 

S = '   I will  go to           the   cinema'

newS = regexprep(strtrim(S), '\s+', ' ')

newS = 'I will go to the cinema'
