I think of dynamic file names as somewhat different from dynamic variable names, as the file names are usually themselves data (passed into a function that reads the file contents then returns a variable whose name is not necessarily tied to the file name, or performs some other operation on the file.) struct1 has many sub structs but lets just assume that im trying to create a new structure using the character values from one of the fields of the old structure. You can say: fName = 'doug' a. The method I used was to add a function equivalent to: * as above, but both options throw an error because the result is not a valid variable name. Your code is a little confusing because it doesn't appear that you are assigning anything to the structure.

For example, they want to store labels and data associated with these labels, and use the labels as field names, when a cleaner and more efficient approach consists in storing data in a numeric array, and labels in a cell array. sites are not optimized for visits from your location. In MATLAB 6.5 (Release 13), we introduced dynamic field references into MATLAB. Better way to check if an element only exists in one array, Disconnect vertical tab connector from PCB, Books that explain fundamental chess concepts. names = fieldnames (s) returns a cell array of strings containing the structure field names associated with the structure s. names = fieldnames (obj) returns a cell array of strings containing the names of the public data fields associated with obj, which is either a MATLAB, COM, or Java object.
