How to remove additional comma from string?

tdat = ["t1,t2,t3", "d2,d3,d4,"]'

How can I remove the extra comma delimiter from string above so result is

tdat = ["t1,t2,t3", "d2,d3,d4"]'

Thanks

What have you tried? There are general purpose functions that can do this, as well as string specific functions.

tdat = ["t1,t2,t3"; "d2,d3,d4,"]

tdat = 2×1 string array
    "t1,t2,t3"
    "d2,d3,d4,"

tdat = regexprep(tdat,',+$','')

tdat = 2×1 string array
    "t1,t2,t3"
    "d2,d3,d4"

Try endsWith and extractBefore like this:

tdat = ["t1,t2,t3",  "d2,d3,d4,"]'

tdat = 2×1 string array
    "t1,t2,t3"
    "d2,d3,d4,"

for k = 1 : numel(tdat)
    if endsWith(tdat(k), ',')
        strLength = length(char(tdat(k)));
        tdat(k) = extractBefore(tdat(k), strLength)
    end
end

tdat = 2×1 string array
    "t1,t2,t3"
    "d2,d3,d4"

tdat

tdat = 2×1 string array
    "t1,t2,t3"
    "d2,d3,d4"
