Symbolic Variables and expressions:
The MATLAB has a type known as sym for the symbolic variables and expressions; these work with strings. The illustration, to generate a symbolic variable a and execute the addition, at first a symbolic variable would be generated by passing the string 'a' to the sym function:
>> a = sym('a');
>> a+a
ans =
2*a
Also the Symbolic variables can store expressions. For illustration, the variables b and c store symbolic expressions as:
>> b = sym('x^2');
>> c = sym('x^4');
Tracing of Square matrices: The trace of a square matrix is the addition of all the elements on the diagonal. For illustration, for the preceding matrix it is 1 + 6 + 11 + 16,
Function cellplot - Cell array: The function cellplot place a graphical display of the cell array in a figure Window; though, it is a high-level view and fundamentally just di
Function fieldnames - structure functions: The function fieldnames will return the names of the fields which are contained in the structure variable. >> pack_fields = fiel
num2str function: The num2str function, that converts real numbers, can be called in many ways. If only the real number is passed to the num2str function, it will generate a s

IS Functions for Strings: There are many functions for strings, that return logical true or false. The function isletter returns the logical true when the character is a lette
Scaling: change a row by multiplying it by a non-zero scalar sri → ri For illustration, for the matrix:
Subfunctions: Though, it is possible to have more than one function in a given M-file. For illustration, if one function calls the other, the first function would be the prima
Execution steps: Whenever the program is executed, the steps below will take place: The script calcandprintarea starts executing. The calcandprintarea calls the readr
