How would you write this C++ script to Matlab?
do k = No_TimeSamples
do i = No_Pixels
SUM_1 = 0
SUM_2 = 0
do j = 1, No_Geophones
delay = R(i, j)/c
ik = round(delay/dt + k)
SUM_1 = SUM_1 + Data(ik, j)
SUM_2 = SUM_2 + Data(ik, j)**2
end
image(i) = image(i) + SUM_1**2 - SUM_2
end
end

?
That is not C++. It looks like Fortran to me.
Is No_TimeSamples a vector? Should we assume that k is to assume each value stored in No_TimeSamples in turn? Or should we assume that k is to assume only the one value stored in No_TimeSamples? Or should we assume that k is to assume the values from 1 to No_TimeSamples ?
Are you certain that the lower bound for the do j loop should be lower-case L, and not i or 1 ?

for k = No_TimeSamples
for i = No_Pixels
SUM_1 = 0;
SUM_2 = 0;
for j = 1 : No_Geophones
delay = R(i, j)/c;
ik = round(delay/dt + k);
SUM_1 = SUM_1 + Data(ik, j);
SUM_2 = SUM_2 + Data(ik, j).^2;
end
image(i) = image(i) + SUM_1.^2 - SUM_2;
end
end
Note: naming a variable image is not recommended, as it interferes with using the image() display function and confuses readers.
