Curve relativity analyze for relationship between blood pressure and atmospheric temperature using Matlab

摘要

This paper analyzed the relationship between atmospheric temperature and blood pressure, and found out the correlation coefficients atmospheric temperature affect on blood pressure. It used Matlab as a tool and adopt cosine vector angle to quantitative analysis, and adopt FFT (Fast Fourier Transform Algorithm) transform to frequency spectrum space to qualitative analysis. It has account the correlation coefficients and testified the validate of them, and give many figures made by Matlab that can give visually relationship among the data to reader it has provided a good foundation for the project that analytical system of atmospheric temperature affect to blood pressure.
