Structure Consisting of the Fields
A MATLAB can also solve the sets of equations. In this illustration, the solutions for x, y, & z are returned as a structure consisting of the fields for x, y, & z. The separate solutions are symbolic expressions stored in the fields of structure.
>> solve('4*x-2*y + z=7' , 'x+ y+ 5*z=10' , '-2*x+ 3*y-z=2')
ans =
x: [1x1 sym]
y: [1x1 sym]
z: [1x1 sym]
To refer to the separate solutions, that are in the structure fields, the dot operator is used.
>> x = ans.x
x =
124/41
>> y = ans.y
y =
121/41
>> z = ans.z
z =
33/41
The double function can therefore be used to convert the symbolic expressions to numbers, and store the outcomes from the three unknowns in a vector.
>> double([x y z])
3.0244 2.9512 0.8049
5 p2+8p+15, 3 p2-3p-18, 12 p2-p-30
Print an imaginary number: To print an imaginary number, the function disp will show both parts automatically: >> disp(z1) 4.0000 + 2.0000i The function fprint
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
Applications of Customized Strings: Labels, Prompts, Arguments to Functions: The one of very useful application of this is to involve numbers in strings that are used to plot
Built in recursive function in MATLAB: We have seen that the built-in function in MATLAB to compute factorials, termed as the factorial and we know how to implement the iterat
Complex numbers: A complex number is commonly written in the form z = a + bi here a is known as the real part of the number z, b be the imaginary part of z, and i is √-1
Illustration of Advanced file input and output: For illustration, to refer to the third number in the first element of the cell array: >> subjdata{1}(3) ans =
Function isreal - complex numbers: The function isreal returns 1 for logical true when there is no imaginary part of the argument, or 0 for false when the argument does have a
Writing to Files: There are many lower level functions which can write to files. We will focus on the fprintf function that can be used to write a file and also to append to a
