Matlab reads EXCEL intelligent algorithm data file

#前言
In the artificial intelligence control and performance forecasting project for a steel company, a large amount of data needs to be processed. I feel that this piece of code may be useful to everyone, so I posted it.
When using intelligent algorithms for classification or regression, it is necessary to first construct the input matrix and output matrix required by the algorithm model, or a data set. The data saved format is often EXCEL, CSV or TXT, which requires us to write code to read out the data.

[loadNumIn,loadTxtIn]=xlsread(‘composition.xls’,‘20Cr’,‘A2:X500’);

This project is an artificial intelligence control and performance forecast for steel companies, which requires a large amount of data to be read out and processed. Reading is only the first step. If you are interested, you can contact me for other codes. Email: [email protected],.cn
