Please help me to solve this two Tasks by MATLAB

Task 1

A)Prompt the user to enter a matrix of numbers of any dimension and determine;

i.The dimensions of the entered matrix.

ii.The summation of each column by using:

A.For loop. (Note: use the entered matrix itself as index for the loop. This is explained in page 4 in this document).

B.While loop to sum the columns. (Use a counter variable i that is equal to the number of columns of the input matrix and determine the sum of the i^th column directly by selecting the whole column by the index number.

iii.The summation of each row by using the procedures A and B on the transposed version of the input matrix. (Note: the columns of the input matrix become the rows of the transposed matrix).

Task 2

A Fibonacci sequence is composed of elements created by adding the two previous elements. The simplest Fibonacci sequence starts with 1 and proceeds as follows: ?

1, 1, 2, 3, 5, 8, 13, ...

?However, a Fibonacci sequence can be created with any two starting numbers. Fibonacci sequences appear regularly in nature. For example, the shell of the chambered nautilus grows in accordance with a Fibonacci sequence. ?

Write a script that displays the elements of Fibonacci sequence that are between two numbers entered by the user.

The script should follow the following pseudo-code:

* Prompt the user for two numbers a and b.

* If a < b proceed otherwise display an error message: Sorry the lower interval limit is to be entered first.. Try again !

*

Generate all Fibonacci number starting from 1 till reaching b. The last Fibonacci element should be less or equal to the upper limit number b.

*Use the find command to select the elements between a and b.

%%For example:

*If the user enters 4 and 8 the results will be [5 8]

*If the user enters 6 and 6 the result should be interval is too short or no Fibonacci numbers are found

*If the user enters 5 and 4 the result should be
