How to put spaces between the elements inside a char array

Hello, gyus :)

Let's say I have a char array like:

data = [ format_time, ' ', format_data, ' ', '\r\n'];

where

format time = %4d %4d %2d

( There are spaces between the formats)

and

format_data = %6.3f%6.3f%6.3f%6.3f%6.3f%6.3f%6.3f%6.3f

( there are not spaces)

and the output is something like : %4d %4d %2d %6.3f%6.3f%6.3f%6.3f%6.3f%6.3f%6.3f%6.3f

The data from format_data are stored by using xlsread function from excel,

otherwise my outputs are joined

I forgot to mention that

format_time = ' %4d %4d %2d' - is written manualy

format_data = [format_XT{:}]

where format_XT is an array with the data from excel

Could you please specify what is your exact input and what result do you want to get? Do you only want to add spaces to your format_data?

Try this below it might help:

format_data = '%6.3f%6.3f%6.3f%6.3f%6.3f%6.3f%6.3f%6.3f';

format_data = strrep(format_data,'%',' %');
format_data(1) = '';
