I want to resize for the highest dot from Y coordinate (5 x 10*4) to 100

pure_brain = readmatrix('Pure Brain Spectra.csv');
[pks,locs] = findpeaks(pure_brain(:,2));  
x = 1:size(pure_brain,1);
[pks_min,pks_max] = bounds(pks)                                         % Minimum & Maximum Values Of ‘pks’
figure
Lv = pure_brain(locs,2)>1E+4;                                           % Set Threshold = 1E+4
% Lv = pure_brain(locs,2)>1;                                              % Set Threshold = 1
plot(x(locs(Lv)), pure_brain(locs(Lv),2), '.r')
grid
title('Pure brain peak');
AB=unique(pks);
YB1=AB(end);                   %1Y
YB2=AB(end-1);                 %2Y
YB3=AB(end-2);                 %3Y
EB1=find(pks==YB1);
XB1=locs(EB1);
EB2=find(pks==YB2);
XB2=locs(EB2);
EB3=find(pks==YB3);
XB3=locs(EB3);
SYB = [ YB1 YB2 YB3 ];
SXB = [ XB1 XB2 XB3 ];
