I would like to change the name of this image:
'name_of_figure_BN_102.png'
to this name:
'name_of_figure_NB_102.png'
I tried splitting the name with 'strsplit' but it doesn't apply to my picture name because there is this '_' symbol.
Is there a simple method to change the name?

My way to do so would be as follows:
str1 = "name_of_figure_BN_102.png"; % Your input image name
strPieces = strsplit(str1,"_") % Splitting the name into pieces
strPieces = 1×5 string array
"name" "of" "figure" "BN" "102.png"
strPieces(4) = "NB" % Editing "BN" to "NB"
strPieces = 1×5 string array
"name" "of" "figure" "NB" "102.png"
% Reconstructing the name again
str2 = strcat(strPieces(1),"_", strPieces(2),"_", strPieces(3),"_", strPieces(4),"_", strPieces(5))
str2 = "name_of_figure_NB_102.png"
I am certain that there is a better way of reconstructing str2 and also there is a way to detect BN's position (and automatize this process). I only had few minutes to make this up. Hope it helps.

Here is one way:
fileName = 'name_of_figure_BN_102.png';
underlineLocations = strfind(fileName, '_')
underlineLocations = 1×4
5 8 15 18
index1 = underlineLocations(end-1) + 1;
index2 = underlineLocations(end) - 1;
fileName(index1 : index2) = fliplr(fileName(index1 : index2))
fileName = 'name_of_figure_NB_102.png'
