楼上说的有问题, The variable y does not exist意思是变量y不存在 还有,不能直接对函数文件运行,函数要放在主文件里调用才可以
1 name 可以是变量名,如果存在,返回值 2 函数名、m 文件名,存在则返回值 3 mex 文件、dll 文件,存在则返回值 4 内嵌的函数,存在则返回值 5 p码文件 , 存在则返回值 6 目录,存在则返回值 7 路径,存在则返回值 8 Java class,存在则返回值 A = exist('name','kind')name 可以是...
matlab::engine::MATLABExecutionException The property does not exist. Examples This example evaluates a MATLAB statement in a try/catch block using MATLABEngine::eval. The MATLABEngine::getVariable member function returns the exception object. MATLABEngine::getProperty returns the exception message prope...
在Matlab脚本文件中可以利用Comsol API 语法轻松地将Matlab计算的单值传递给Comsol中的任何变量或属性(例如: model.variable('var1').set('E', num2str(E0))" 可将计算值E0传递给comsol中的变量E)。但如何将Matlab中计算的数组(该数组与Comsol中场变量同大小)传递给Comsol中的变量呢?当然,通过全局定义外部Matlab...
routine, that MATLAB is permitted to assume that the name only refers to a variable, and then to complain when the variable does not yet exist at the time that the name was intended to be a function call. You need to edit the code so that uses some other variable name rather than...
0—namedoes not exist or cannot be found for other reasons. For example, ifnameexists in a restricted folder to which MATLAB®does not have access,existreturns 0. 1—nameis a variable in the workspace. 2—nameis a file with extension.m,.mlx, or.mlapp, ornameis the name of a file...
ParallelR.m is a valid matlab filename, whereas Parallel R.m is not. Practice Problems 1. Create a script called CurrentSolverthat expects to have the variables V and R defined. It should create a variable called I and set it equal to the current defined by Ohm’s Law: V = IR. ...
% To obtain dual variable for a constraint, use DUAL. % % See YALMIPERROR for error codes returned in output. % % OUTPUT % diagnostic : Diagnostic information % % INPUT % F : Object describing the constraints. Can be []. % h : SDPVAR object describing the objective h(x). Can be ...
Variable names tell what the variable does Undoubtedly, this is the first and foremost rule in variable naming, and it implies several things. Of course, you would not name a variablepiwhen it really holds the value2.718128, right? In mathematics and computer science, some names are connected...
If this environment variable is set, the engine's working directory will be changed to match the kernel's working directory. IMATLAB_CONNECTneeds to be set outside of MATLAB (as it is checked before the connection to the engine is made). Other environment variables can be set either outsid...
