Explore MATLAB source code curated for "曲线" with clean implementations, documentation, and examples.
With 100 data points containing known x, y, and z coordinates, this guide demonstrates how to fit these points into a spatial curve using command-line approaches. Based on the point distribution resembling a helix, we'll derive a mathematical expression to represent the curve, complete with implementation programs and algorithm explanations.
A custom MATLAB program that computes linear regression parameters (slope k and intercept b) from given x and y coordinate datasets. The implementation utilizes matrix operations and linear algebra principles for accurate results.
"SLM_Papr_V4.m" generates the Complementary Cumulative Distribution Function (CCDF) curve for Peak-to-Average Power Ratio (PAPR) using Selected Mapping (SLM) technique version 4, featuring code implementation for phase sequence generation and OFDM signal processing with PAPR reduction analysis.
When certain data points in a curve are excessively large, making VC plots visually unappealing, you can apply reduction techniques while preserving trend information through appropriate algorithms and scaling methods.
This section of code utilizes curvature relationships to extract concave point counts and determine curve curvature, providing a method for analyzing various graphical data patterns through concavity feature extraction.
