Would you please help me to show m_{NPV} with their subscripts as below:

VariableNames={'\sigma_{1}','\sigma_{2}','\sigma_{3}','\tau_{1}','\tau_{4}','\tau_{5}','m_{NPV}'};

So, I have this code which works but I do not know how to fix m_{NPV}

% your example code
Fields      = [1, 4, 5]; 
Fields_time = Fields +16;
MT_All      = rand(100,26);
% MT_All = rand(100,9);
VariableNames={'sigma','sigma','sigma','tau','tau','tau','mNPV'}; % changed to ensure valid syntax
Mat_All_1_4_5 = [MT_All(:,Fields), MT_All(:,Fields_time), MT_All(:,end-1)]; 
figure
corrplot(Mat_All_1_4_5, 'varNames', VariableNames);
% get current figure handle
fh = gcf;
% find x and y label strings that are not empty within subplots
yLabelN = find(cell2mat(arrayfun(@(dIn)~isempty(dIn.YLabel.String),fh.Children,'UniformOutput',false)));
xLabelN = find(cell2mat(arrayfun(@(dIn)~isempty(dIn.XLabel.String),fh.Children,'UniformOutput',false)));
% rename y labels
% indSig = 0;
% for ik = 1:length(yLabelN)
%%
for ik = 1:length(Fields)
    if strfind(fh.Children(yLabelN(ik)).YLabel.String,'sigma')
%         indSig = indSig + 1;
        fh.Children(yLabelN(ik)).YLabel.String = strrep(fh.Children(yLabelN(ik)).YLabel.String,'sigma',sprintf('\\sigma_{%d}',Fields(ik)));
    end
    
    if strfind(fh.Children(yLabelN(ik+length(Fields))).YLabel.String,'tau')
%         indSig = indSig + 1;
        fh.Children(yLabelN(ik+length(Fields))).YLabel.String = strrep(fh.Children(yLabelN(ik+length(Fields))).YLabel.String,'tau',sprintf('\\tau_{%d}',Fields(ik)));
    end
    
%     if strfind(fh.Children(yLabelN(ik+length(Fields))).YLabel.String,'m')
% %         indSig = indSig + 1;
%         fh.Children(yLabelN(ik+length(Fields))).YLabel.String = strrep(fh.Children(yLabelN(ik+length(Fields))).YLabel.String,'m',sprintf('\\tau_{%d}',Fields(ik)));
%     end
    
end
%%
% strrep(fh.Children(yLabelN(ik)).YLabel.String,'t_','t^{*}_{1}')
% rename x labels
ik = 1:length(xLabelN)
for ik = 1:length(Fields)
    if strfind(fh.Children(xLabelN(ik)).XLabel.String,'sigma')
        fh.Children(xLabelN(ik)).XLabel.String = strrep(fh.Children(xLabelN(ik)).XLabel.String,'sigma',sprintf('\\sigma_{%d}',Fields(ik)));
%         indSig = indSig - 1;
    end
    
    if strfind(fh.Children(xLabelN(ik+length(Fields))).XLabel.String,'tau')
        fh.Children(xLabelN(ik+length(Fields))).XLabel.String = strrep(fh.Children(xLabelN(ik+length(Fields))).XLabel.String,'tau',sprintf('\\tau_{%d}',Fields(ik)));
%         indSig = indSig - 1;
    end
    
end

c = corrplot(Mat_All_1_4_5, 'varNames', VariableNames);
% get current figure handle

% find x and y label strings that are not empty within subplots

    if ik <= 3
        fh.Children(yLabelN(ik)).YLabel.String = sprintf('\\sigma_{%d}',Fields(ik));
        fh.Children(xLabelN(ik)).XLabel.String = sprintf('\\sigma_{%d}',Fields(ik));
