Abstract: A texture data analysis method based on Matlab was introduced, through the secondary programming of MTEX, an open source project of Matlab, realizing the data analysis function of silicon steel texture. It can break away from the limitations of equipment, software and space, and conveniently deal with EBSD and XRD texture data, including data noise reduction, drawing (BC, IPF, PF, ODF, KAM), calculation of texture proportion, average grain size and grain size distribution. 

Key words: Matlab, MTEX, texture data analyse, silicon steel
