I have a quaestion. Which command should I use in order to replace () with -.

for example I have strigs in an array like :

America (New York)
America (Manhattan)
Italy (Rome)

And I would like my output strings to be:

America - New York
America - Manhattan
Italy - Rome

Which command shouls I use? I tried strrep but no use.

Could you please help me?

Here are two approaches:

A = ["America (New York)"; "America (Manhattan)"; "Italy (Rome)"]
A = 3×1 string array
    "America (New York)"
    "America (Manhattan)"
    "Italy (Rome)"
B = strrep(strrep(A,' (',' - '),')','')
B = 3×1 string array
    "America - New York"
    "America - Manhattan"
    "Italy - Rome"
B = regexprep(A,'^(.+?)\s*\((.+)\)$','$1 - $2')
B = 3×1 string array
    "America - New York"
    "America - Manhattan"
    "Italy - Rome"
