There are two options to store the matrix: (i) in model.quadcon(i).Qc as a sparse matrix; (ii) through three dense vectors model.quadcon(i).Qrow, model.quadcon(i).Qcol, and model.quadcon(i).Qval specifying the matrix in triple format, with row indices, column indices, and ...
5.2.1 单个字符 上一小节提过:字符(char)是文本的最基本单元。在MATLAB中,单个字符使用单引号引起来,例如:'a'、'0'、'我'。(一定要是英文输入法下的单引号,中文的会报错) 下面我们介绍两个简单的函数,它能实现字符和对应的Unicode编码的转换。 double函数可以获取字符对应的Unicode编码(十进制)。 char函数可以...
