varExists(i) indicates whether the variable name varNames(i) exists in the connected data source. If a data connection can access multiple data sources (for example, a data dictionary and its referenced dictionaries), the function returns 1 (true) if the variable exists in any of the ...
When you start MATLAB usingmatlab-proxy, MATLAB will first run astartup.mfile, if one exists on your path. For details, seeUser-defined startup script for MATLAB. MATLAB will then run any code you have provided as a string to theMWI_MATLAB_STARTUP_SCRIPTenvironment variable. ...
For objects, assign the variable name in theDiscrete Filter (orQuantized Filter)text box. If you have variables with the same names in your workspace and you want to overwrite them, select theOverwrite Variablescheck box. Click theExportbutton. The Export to a MAT-File dialog box appears. ...
(1 point)Theory: A matrix A is said to be orthogonally diagonalizable if there exists an orthogonalmatrix P ( 1 T P P = ) and a diagonal matrix D, such that, 1 A PDP = , or equivalently,T A PDP = .Theorem: An n n matrix A is orthogonally diagonalizable if and only if A is...
