Numerical Integration with Data Points Using Simpson's 1/3Rule,Trapezoidal Rule,and Composite Trapezoidal Rule in MATLAB
This program was developed based on personal needs and allows for numerical integration of multiple x-values and their corresponding function values using Simpson's 1/3 Rule, Trapezoidal Rule, and the Composite Trapezoidal Rule. The only input required from the user is in lines 2 and 3, where they must insert their data points. For example:?ta Input: x = [1,2,3]; y = [2,2,3];This method is much faster than using an online calculator, where you have to wait a few seconds to see the result. :)

Imprecise Alternating Optimization for Phase Retrieval with Outliers Robust Phase Retrieval Demonstration Using AltGD in MATLAB
C. Qian, X. Fu, N.D. Sidiropoulos, L. Huang, and J. Xie explore phase retrieval in the presence of outliers in their paper published in the IEEE Transactions on Signal Processing. Typically, phase retrieval algorithms perform well under Gaussian noise; however, their performance severely degrades with significant data corruption. This study investigates heavy-tailed phase retrieval techniques, proposing p-norm estimators (0 < p>imprecise alternating optimization are introduced to tackle the resulting optimization problem. Notably, the core minimization step can be interpreted as iterative reweighted least squares and gradient descent. The authors discuss the convergence properties of the algorithms and derive the Cramer-Rao Bound (CRB). Simulations demonstrate that the proposed algorithms are effective and close to optimal.

MATLAB Code for Cross Sectional Area Analysis from Time Series Data in Excel
This MATLAB code imports time-series data related to riverbank and water depth coordinates in XY format, sampled every 10 minutes. The code calculates the cross-sectional area for each water depth and writes the following data to an Excel file: Date/Time, Water Depth, and the cross-sectional area for each water depth.
