Hello

Can you help me to create function for this script?

%%Center of mass at 30second

F_sum4 = 0;

start=1;

stop=810;

for n = start:stop

F_sum4 = F_sum4 + F(:,:,n)

CY_sum4 = mean(cy_sum(start:stop),'omitnan')

CX_sum4 = mean(cx_sum(start:stop),'omitnan')

% if rem(m,27)==0

end

imshow(F_sum4,[]); hold on

plot(CX_sum4,CY_sum4,'*','markersize',30)

hold off

F_sum5 = 0;

start=810;

stop=1620;

for a = start:stop

F_sum5 = F_sum5 + F(:,:,a)

CY_sum5 = mean(cy_sum(start:stop),'omitnan')

CX_sum5 = mean(cx_sum(start:stop),'omitnan')

% if rem(m,27)==0

end

imshow(F_sum5,[]); hold on

plot(CX_sum5,CY_sum5,'*','markersize',30)

F_sumA= F_sum4+F_sum5

imshow(F_sumA,[]); hold on

plot(CX_sum4,CY_sum4,'*','markersize',30)

plot(CX_sum5,CY_sum5,'*','markersize',30)

%plot(CX_sum4,CY_sum4,'*','markersize',30)

% plot(CX_sum,CY_sum,'*','markersize',30)

hold off

Simplify

F_sum4 = 0;
start=1;
stop=810;
for n = start:stop
    F_sum4 = F_sum4 + F(:,:,n)
    CY_sum4 = mean(cy_sum(start:stop),'omitnan')
    CX_sum4 = mean(cx_sum(start:stop),'omitnan')
end

to

start   = 1;
stop    = 810;
F_sum4  = sum(F(:,:,start:stop), 3);
CY_sum4 = mean(cy_sum(start:stop),'omitnan')
CX_sum4 = mean(cx_sum(start:stop),'omitnan')
