mustBeValidVariableName(varname)validate that input name is a valid variable name. This function does not return a value. mustBeValidVariableNamecalls the following function to determine if the input is a valid
Show that input that starts with a number is not a valid variable name. s ='8th_column'; isvarname(s) ans =logical0 Change the input to a valid variable name. s ='column_8'; isvarname(s) ans =logical1 Use the command form to determine if the input is a valid variable name. ...
最近也在接受一下非电子类的培训，也是艰难的不行，感觉是真的去搬砖了一样，
5 = 6;% If this worked, it would define a variable named 5 whose value was 6. There arefunctions you can use to convert identifiersthat are not valid variable names into valid variable names. See matlab.lang.makeValidName (or if you're using an older release, GENVARNAME.) ...
