Use figure PaperPositionMode setting: Uses the PaperPositionMode property of the Handle Graphics В® figure to set the image size in the report. H = subplot(m,n,p), or subplot(mnp), breaks the Figure window into an m-by-n matrix of small axes, selects the p-th axes for the current plot, and returns the axes handle.

Here we consider two standard functionsВ tandВ andВ cosd, which we can use directly in the program.Matlab figure background white % MATLAB code for Change background to GRAY.

#Function matlab how to#

Program (1): To demonstrate how to access standard functions without import keyword. MATLAB having large numbers of built-in function and you can directly call these function using your intuition. Program (1): % primary function definition Each sub-function should have its own function definition line. The first function is the primary function and remaining functions are called sub-functions. M-file can contain code for more than one function.

Program (1): % defining anonymous function

anony_name is the name of the anonymous functionДЄim (1): To demonstrate anonymous function that gives half of a number.

The general form of an anonymous function is anony_name = expr This type of function can be constructed either at MATLAB command window or in any M-file function or script.

The func_name represent the function name.

()) represent arguments value accept from the user will go to functionвЂ™s body.

x=3 and z=4, along with x=4 and z=6В gives results as > d = func_name(,) We can also call function func_name with more than one values of each variable i.e. When we call function func_name with x=3 and y=4, gives results as > d = func_name(2,4) The function definition is given by function y = func_name(x,z) The example below will show the way of writing this type of function in MATLAB programming. In this type of function, we can pass more than one arguments to calling function as well as can receive any data from the calling function. Hence, the output is 2.ДЇunction with multiple argument pass and return values The input inside the parameters as 4 compare with the input specified as n in the function file half.m definition. MATLAB look for a function file half.m.The function half.m that we already created earlier and now we call it. When function is call, it passes any argument (parameters) to calling function. The function call really calls the function. n inside function name half(n), is the input argument.

The function keyword represents the beginning of the function definition.

The function definition in MATLAB is given by function y = half(n) The function definition having the statement(s) which executes when function called and after that function returns back to calling function. When we write function structure generally having two parts as function call and function definition. In MATLAB, a large program divides into subprogram for performing a specific task and this subprogram is called function. After reading the MATLAB Functions topic, you will understand function structure, anonymous functions, and sub-functions in MATLAB.
