PCA
函数作用:
cwstd.m——用综合标准化法标准化矩阵
Cwfac.m——计算相关系数矩阵,计算特征向量和特征值,对主成分进行排序,计算各个特征值的贡献率,挑选主成分(贡献率达与85 ),输出主成分个数,计算主成分载荷
Cwscore.m——计算各主成分得分,综合得分并排序
Cwprint.m——读入数据文件,调用以上三个函数,并输出结果
原始数据:存储在src.txt中是一个30×8的矩阵
敲入命令:
(PCA)

ieee754_32
Converts a floating point value to IEEE 754 32 bit binary representation.
Sign Bit: 1
Exp: 2 to 9
Frac: 10:32
Single-precision floating-point format is a computer number format that occupies 4 bytes (32 bits) in computer memory and represents a wide dynamic range of values by using a floating point. In IEEE 754-2008 the 32-bit base 2 format is officially referred to as binary32. It was called single in IEEE 754-1985. In older computers, other floating-point formats of 4 bytes were used.
For example, the 32-bit floating point bit pattern 1 01111101 00101100000000000000000 is interpreted as the following:
(− 1)1 × (1 + 0.34375) × 2(125–127) = -1.34375× 2− 2 = -0.3359375
