I have solved some equations and exported the final results, which they are several Matrices, as a EXCEL file ( .Xls ). Now, I want to use these EXCEL files as my inputs to solve some other equations. I use Import[]
to read these EXCEL files. But when I import them, these Matrices appears like this :
{"ÐÏ\.11à¡\[PlusMinus]"}
When I use Import[exp,"Table"]
or Import[exp,"List"]
the results are exactly same as previous one.
I don't know what the problem is ?!
This is part of the code :
AA = Import["C:\\Users\\Com\\Desktop\\EXCEL\\AA.Xls", "List"];
BB = Import["C:\\Users\\Com\\Desktop\\EXCEL\\BB.Xls", "List"];
CC = Import["C:\\Users\\Com\\Desktop\\EXCEL\\CC.Xls", "List"];
ssm = StateSpaceModel[{AA, BB, CC}]
The results :
During evaluation of In[8]:= StateSpaceModel::farg: {{ÐÏ\.11à¡\[PlusMinus]}, {ÐÏ\.11à¡\[PlusMinus]},{ÐÏ\.11à¡\[PlusMinus]}} is not a valid TransferFunctionModel or a list of state-space matrices in the form {a, b, ...}. >>` During evaluation of In[8]:= StateSpaceModel::farg: {{ÐÏ\.11à¡\[PlusMinus]}, {ÐÏ\.11à¡\[PlusMinus]},{ÐÏ\.11à¡\[PlusMinus]}} is not a valid TransferFunctionModel or a list of state-space matrices in the form {a, b, ...}. >> StateSpaceModel[{{"ÐÏ\.11à¡\[PlusMinus]"}, {"ÐÏ\.11à¡\\[PlusMinus]"}, {"ÐÏ\.11à¡\[PlusMinus]"}}]`
TableForm
andTake
orPart
to view your matrices inside Mathematica. Furthermore, note that adding a second argument toImport
like "List" or "Table" should not be necessary in this case. To save your matrices to the hard disk, seeDumpSave
andSave
, or try directly toExport
to the formats .mx .m.Dumpsave
andExport
to .mx create computer dependent versions. File created by Save and .m files can shared between computers. $\endgroup$matrix = First@Import[fileName];
$\endgroup$Import[filePath, "Elements"]
. This shows you all the valid strings that can be used as second arguments. Here I think "Data" is the default. $\endgroup$
