How do you combine strings?
You concatenate strings by using the + operator. For string literals and string constants, concatenation occurs at compile time; no run-time concatenation occurs. For string variables, concatenation occurs only at run time.
How do I merge two characters in MATLAB?
Combine Character Vectors Create two character vectors, with the first character vector having a trailing whitespace character. chr1 = ‘Hello ‘; chr2 = ‘World’; Combine them into one character vector. The append function always preserves trailing whitespace characters, unlike the strcat function.
How do you remove trailing spaces from a string?
String result = str. The trim() method will remove both leading and trailing whitespace from a string and return the result.
How do you trim a character array?

To replace an element in an array:
- Use a for loop to iterate for array. length times.
- On each iteration, check if the array element at the current index is the element to be replaced.
- If the condition is met, replace the element at that index and break out of the for loop.
