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');
Scaling: change a row by multiplying it by a non-zero scalar sri → ri For illustration, for the matrix:
Intersect function and setdiff function: The intersect function rather than returns all the values which can be found in both of the input argument vectors. >> intersect(v
Interpolation and extrapolation: In most cases, it is desired to estimate values other than at the sampled data points. For illustration, we may want to estimate what the temp
function numden: The function numden will return individually the numerator & denominator of a symbolic expression: >> sym(1/3 + 1/2) ans = 5/6 >> [n, d] =
Example of Gauss-jordan: For a 2×2 system, this would results and for a 3 × 3 system, Note that the resulting diagonal form does not involve the right-most col
Related Structure Functions: There are many functions which can be used with structures in a MATLAB. The function isstruct will return 1 for logical true when the variable arg
Creating the structure Variables: Creating a structure variable can be accomplished by simply storing the values in fields by using assignment statements, or by using the stru
Passing arguments to functions: In all these functions examples faraway, at least one of the arguments was passed in the function call to be the value(s) of the equivalent inp
Algorithm for the function explaine: The algorithm for the function explaine is as shown: Print a description of e, the exp function, and how to find the approximate va
Set Operations: The MATLAB has numerous built-in functions which perform set operations on vectors. These involve intersect, union, setdiff, unique, and setxor. All these func
