Most likely you meant to write a + b, but you wrote a +b This can easily lead to bugs, as [a +b] is a vector with two elements If you really want to use unitary plus, you will have to edit sdpvar/uplus and delete this message 错误使用 solvesdp_multiple (第 8 行) Parts of your matrix objective is not linear (multiple solutions can currently only be obtained for linear objectives) 出错 solvesdp (第 17 行) diagnostic = solvesdp_multiple(varargin{:}); 出错 optimize (第 31 行) [varargout{1:nargout}] = solvesdp(varargin{:}); 出错 Model (第 202 行) sol = optimize(Constraints, -TR, options); 这是什么问题

这是一个MATLAB错误，其中包含了三个不同的错误信息。下面分别解释：

1. "Most likely you meant to write a + b, but you wrote a +b This can easily lead to bugs, as [a +b] is a vector with two elements If you really want to use unitary plus, you will have to edit sdpvar/uplus and delete this message" 这个错误信息表示您在代码中使用了一个不规范的加号写法，可能会导致错误。如果您确实需要使用加号写法，您需要修改sdpvar/uplus函数并删除这个提示信息。

2. "错误使用 solvesdp_multiple (第 8 行) Parts of your matrix objective is not linear (multiple solutions can currently only be obtained for linear objectives)" 这个错误信息表示您在使用solvesdp_multiple函数时，目标矩阵中的某些部分不是线性的。目前，多个解只能用于线性目标。您需要检查您的目标矩阵，并确保它是线性的。

3. "出错 solvesdp (第 17 行) diagnostic = solvesdp_multiple(varargin{:}); 出错 optimize (第 31 行) [varargout{1:nargout}] = solvesdp(varargin{:}); 出错 Model (第 202 行) sol = optimize(Constraints, -TR, options);" 这个错误信息是由于前面的两个错误导致的，它表示在求解器solvesdp中出现了错误，这个错误最终导致了模型优化失败。

您需要检查您的代码，并修复所有的错误信息，以便成功运行您的MATLAB程序。
