Hello everyone,
I Have an excel data with with two rows. I am trying to do a numerical integration of the data using gauss. Is their any way to do the integration? I dont have any function or expression to solve the data. It is just a numerical data. I have already worked using cumtrapz. But I am trying to do the same using gauss. I am attaching the data. Please kindly help me. Thanks in advance.
With regards,

Hello @Mathieu NOE,
Thank you for your response. I took a look at the Gauss numerical integration. But I dont have weight residuals and zeta values. Apart from that I dont have a function, I jus had d following data.
