What is the sum of the first digit of all primes less than or equal to 11111? Hint: You may want to use the num25tr() and str2num() functions. The sum of the first digit of each prime is 19 (i.e. Learn the basics of MATLAB® through this introductory tutorial on commonly used features and workflows.In MATLAB, primes(N) provides all the prime numbers less than or equal to N. Hidden object handles are still valid.Get started with the MATLAB language and environment so that you can analyze science and engineering data. Get, findobj, gca, gcf, gco, newplot, cla, clf, and close functions. If the object is not listed in the Children property of the parent, thenįunctions that obtain object handles by searching the object hierarchy or querying This optionīlocks access to the object at the command line, but permits This option is useful for preventing unintendedįrom within callbacks or functions invoked by callbacks, but notįrom within functions invoked from the command line. Otherwise, use the gcbo function to access the object.Īll times. If you specify this property as a function handle or cell array, you can access the object that is being created using the first argument of the callback function. Setting the CreateFcn property on an existing component has no effect. If you do not specify the CreateFcn property, then MATLAB executes a default creation function. MATLAB initializes all property values before executing the CreateFcn callback. This property specifies a callback function to execute when MATLAB creates the object. MATLAB evaluates this expression in the base workspace.įor more information about specifying a callback as a function handle, cell array, or character vector, see Create Callbacks for Graphics Objects. Subsequent elements in the cell array are the arguments to pass to the callback function.Ĭharacter vector containing a valid MATLAB expression (not recommended).

If the data range for either dimension is greater than 1024, ToĪvoid accidentally creating too many bins, you can use this rule to create a Width of 1 for each dimension and places bin edges halfway between integers. The integer rule is useful with integer data, as it creates a bin for each Might be more suitable for data with heavy-tailed distributions. The Freedman-Diaconis rule is less sensitive to outliers in the data, and This rule is appropriate for most other distributions, as well. Scott’s rule is optimal if the data is close to being jointly normallyĭistributed. The default 'auto' algorithm chooses a bin width toĬover the data range and reveal the shape of the underlying
