How to extract a slider value?

%Slider
fig = uifigure('Position',[100 100 350 275]);
pnl1 = uipanel(fig);
sld1 = uislider(pnl1,'Position',[100 40 120 3],... 'ValueChangingFcn',@(sld,event1) slider1(event1));
sld1.Limits = [-100 100];
sld2 = uislider(pnl1,'Position',[100 100 120 3],... 'ValueChangingFcn',@(sld,event2) slider2(event2));
sld2.Limits = [-100 100];
sld3 = uislider(pnl1,'Position',[100 180 120 3],... 'ValueChangingFcn',@(sld,event3) slider3(event3));
sld3.Limits = [-100 100];
I'm trying to make a program to extract the power of my engine from the sliders I declared(each one corresponds to one engine). So I need to extract the value of each slider when i dragg it as an integer variable, if anyone can help it will be great.
Thanks!

@Darío Imbernón Clavero, You can call the ValueChangedFcn property for the uislider function, and define functions for ValueChangedFcn names given inside the uislider function. This will make the slider functions output the slider value accordingly and get rid of the for loop. The sld and event are common input arguments for the slider functions to record the events by user clicks on slider component.
clc
clear all
fig = uifigure('Position',[100 100 350 275])
pnl1 = uipanel(fig)
sld1 = uislider(pnl1,'Position',[100 40 120 3],'ValueChangedFcn',@(sld,event) slider1(event))
sld1.Limits = [-100 100]
sld2 = uislider(pnl1,'Position',[100 100 120 3],'ValueChangedFcn',@(sld,event) slider2(event))
sld2.Limits = [-100 100]
sld3 = uislider(pnl1,'Position',[100 180 120 3],'ValueChangedFcn',@(sld,event) slider3(event))
sld3.Limits = [-100 100]
% call the ValueChangedFcn
a = sld1.ValueChangedFcn;
b = sld2.ValueChangedFcn;
c = sld3.ValueChangedFcn;
% define the functions for ValueChangedFcn names given inside the uislider
function a = slider1(event)
a = event.Value
end
function b = slider2(event)
b = event.Value
end
function c = slider3(event)
c = event.Value
end
