Hallo, Thanks for reading,
I have a character array (1x22222) read from a text file. Using the character vector I would like
to serach for the following line within the array: ( ' * ' here is represented as random text part)
'(:PAR :N CORNERS :DIM (4 2) :V #2A(*)'
After that I would like to replace the text with following line:
'(:PAR :N CORNERS :DIM (4 2) :V #2A((0.0 4.0) (2.5 4.0) (2.5 0.0) (0.0 0.0))'
I have the following lines of code but it cannot find the intended text
f = regexprep(character_array,'(:PAR :N CORNERS :DIM (4 2) :V #2A(*)'],...
'(:PAR :N CORNERS :DIM (4 2) :V #2A((0.0 4.0) (2.5 4.0) (2.5 0.0) (0.0 0.0))');

Please note that ‘(‘ is a special character. For replacing the described lines with the intended text, please replace the expression (second argument of the regexprep function) with:
'\(:PAR :N CORNERS :DIM \(4 2\) :V #2A\(.*?\)'
