The question is not clear. Give a clear example of what you want to do by giving some input data and specifying what your intended output is.

how to use dictionary in matlab to store variable and calling into sub function?

[Stephen23]

Why do you need a dictionary? Basic indexing would probably do what you need.

[chirag patel]

For parameters 50 it is becoming tedious. So help how to use data dictionary.

Hi,

Can you be a bit more descriptive in what you are trying to achieve.

To define a function as a string you can use "str2func()" function and pass the arguments.

As Stephen Cobeldick suggested, it would be better to use a cell array to store values instead of several different variable names.

If this function takes variable number of arguments you can use "varargin" as shown in the code below.

% getDetails is a sample function name. You need to define what the function does elsewhere. 

funcHandle = 'getDetails';  
funcHandle = str2func(funcHandle); 
[output1, output2] = funcHandle(funcHandle, varargin);
