1. Suppose that to build a 3×3 matrix in which the first column contains the sine of the elements between and 27, the second
column contains the sine of the elements between and 37, the third column contains the sine of the elements between and
Two spacing are required between the elements. You are requested to find the determinant and the inverse of the aforementioned
matrix (Hint: Use linspace(a,b,n) to build three rows and transpose of a matrix to find the columns of the aforementioned matrix)
a) Sketch the flow diagram
b) Write the MATLAB Code on the answer sheet to construct this matrix, to find the determinant and the inverse of this matrix.
c) Add explanation (comment) for each line of this MATLAB Code.
d) Run the m-script and show the screenshots on your answer sheet by using the "print screen" button on the keyboard.
e) Discuss what it can be said about the matrix in terms of its determinant and in terms of its inverse.
2. Let you consider the following linear equation system;
- 2x1+5x2 + 4x3-3x4=9
x17x2 + 2x3 + 9x4 = 7
4x1+3x2+8x3-6x4=0
- 6x + 15x2 +12x3-9x4-27
You are requested to solve system if possible.
a) Sketch the flow diagram
b) Write the MATLAB Code on the answer sheet to solve this equation system by finding its determinant and its inverse.

d) Run the m-script and show the screenshots using the "print screen" button on the keyboard.
e) Discuss what it can be said about the matrix in terms of its determinant and in terms of its inverse.
3. It is aimed to count the negative elements of the vector A containing non-decimal numbers between -3 and 10 with 13 intervals
between these numbers and assign the result to variable b, and count the zero and positive elements of the same vector and assign
them to variable c (Hint: Use linspace(x, y, n) to build matrix A).
(a) Draw a Flow Diagram showing the algorithm of the process in question.
(b) Build a MATLAB m-script that executes the algorithm mentioned in (a)
