strcat

Arguments

strings

vector, matrix, or hypermatrix of strings.

string_added

a string added, default value is the zero length character string "".

txt

a string.

"r" | "c" flag

"r" glues together all rows of each column, in the array strings. If strings is a matrix, txt is a row of longer strings. "c" glues all columns of each row.

Description

txt = strcat(strings) concatenates character strings: txt = strings(1) + ... + strings(n).

txt = strcat(strings, string_added) returns txt = strings(1) + string_added + ... + string_added + strings(n).

The plus symbol does the same: "a"+"b" is the same as strcat(["a","b"])..

If the size of strings is one, it returns txt = strings(1);

strcat('A','B') returns 'A' and not 'AB' as strcat(['A','B']).

If strings is a matrix of strings, txt = strcat(strings, "", "r") returns a row vector of strings. Each entry of txt results from the concatenation of rows along the related column. txt = strcat(strings, "", "c") returns a column vector of strings. Each entry of txt results from the concatenation of columns along the related row.

Examples

strcat(string(1:10),',')
strcat(["a","b"])
strcat(["a","b"],'|')
strcat('A')
strcat('A','B')
strcat(['A','B'])
strcat(['A','B'],'')

m =["a" "b" ; "c" "d"];
strcat(m, "r")
strcat(m, "", "r")
strcat(m, "", "c")

strcat(m, "_and_", "r")
strcat(m, "_and_", "c")
