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

It is a vector.
I have a CSV read into matlab with 10 000 time points, & 32 Sensor Channels.
This code generates an image based on data.
R(i, j) is an array.
Data(ik, j) is an array generated from my csv.
image(i) stores the values that generate the image.

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.
