>> cd /path/to/cvx >> cvx_setup 其中,/path/to/cvx是CVX所在的目录。 测试安装:在MATLAB命令窗口中输入以下命令,测试CVX是否安装成功: >> cvx_begin >> variable x(2) >> minimize(norm(x,1)) >> subject to >> x >= 0 >> cvx_end 如果没有错误提示,说明CVX已经安装成功。 注意:CVX需要...
矩阵化编程: 矩阵的逻辑标示法索引方式,和前面提到的算符和表达式的“数组运算”方式结合可以产生强大的“矩阵化”编程方式,用这种方式替代循环结构不仅可以简化代码,还可以大大提高代码执行效率,例子如下。 程序要计算下面的函数: 其中theta在二维下为10/(7*pi*h^2),函数图像如下所示(类高斯函数): 下面比较普通循...
0— name does not exist or cannot be found for other reasons. For example, if name exists in a restricted folder to which MATLAB does not have access, exist returns 0. 1— name is a variable in the workspace. 2— name is a file with extension .m, .mlx, or .mlapp, or name is ...

I'm trying to change directory into two levels of subfolders but am having trouble making cd(variable) accept the input argument. Once into each subfolder, I need to call a function (dirf) that will create a batch file of all files in the cd. ...
You solution is to run matlab with the -nojvm mode. The heap memory system in JAVA consists of data and handle elements. When you allocate a variable you get a handle and data. As long as data has an associated handle, the JVM considers it valid and w 34、ill not clean it up. ...

I keep getting "Variable Ans3 has an incorrect value." for my code how can i fix this? I believe that "AI" refers to the product of A and the (appropriately sized) identity matrix I. Similarly for "CI". See eye for... 23 days ago | 0 | accepted Answered help with nested lo...
