Symbolic Expression
The solve function solves an equation and returns the solution(s) as symbolic expressions. The answer can be converted to numbers by using any numeric function, like double:
>> x = sym('x');
>> solve('2*x^2 + x = 6')
ans =
3/2
-2
>> double(ans)
1.5000
-2.0000
When an expression is passed to the solve function instead of an equation, it will set the expression equivalent to 0 and solve the resulting equation. For illustration, this will solve
3x2 + x = 0:
>> solve('3*x^2 + x')
0
-1/3
If I have a vector representing the packed storage form of a symmetric matrix, how do I perform a cholesky factorisation on that?

Built-in function for Differentiation: The MATLAB has a built-in function, diff that returns the differences between consecutive elements in a vector. For illustration, >>
Error-checking for integers: illustrations of running this script as shown below: >> readoneint Enter an integer: 9.5 Invalid! Enter an integer: 3.6 Invalid
Find Minimum and Maximum for each row To find the maximum (or minimum) for each row, the dimension of 2 (that is how a MATLAB refers to rows) can be identified as the third arg
Writing variables to a File: The save command is used to write variables to a file, or to append the variables to a MAT-file. By the default, save function writes to a MAT-fil
Three-dimensional pie and bar: For the bar3 function, x & y vectors are passed and the function displays three-dimensional bars as shown in figure: Figure: Three-dimen
Concatenation: The String concatenation means to join the strings altogether. Of course, as strings are merely vectors of the characters, the technique of concatenating vector
Blanks function: The blanks function will generate a string consisting of n blank characters-that are kind of hard to see here! Though, in a MATLAB if the mouse is moved to hi
Minimum and Maximum Value The MATLAB has built-in functions for numerous statistics. For illustration, min and max to find the minimum or maximum value in a data set. >> x
