MATLAB: Adding single quotation to a string

Question

Hi everybody,

my code accept just this format of String –> filename='"GComScan_20200115_135716.sdb"' (first and last Quotes are single) why i dont know ?

i have tried with this command to get that, but the result was reverse, means first and last Quotes are dobble " ' ' " (without space).

filename = "'" + string(extractBetween(filename, "Scans\\", filename(end)))+ "'"

Result.

the right one;

How can I solve this issue? Thank you.

Answer 1

filename = sprintf('"%s"',string(extractBetween(filename, "Scans\\", filename(end)))); 

Result:

filename2 = '"GComScan_20200115_135716.sd"'

Explanation:

filename is actually a character array, not a string (see Characters & Strings to understand the difference). The double quotes are part of the character vector. The outer single quotes are not part of the character vector; they actually define the variable as a character vector.

To see the actual content of the filename variable,

>> disp(filename)
"GComScan_20200115_135716.sd"
