If t is a vector how do you assign the following vector in M

If t is a vector, how do you assign the following vector in Matlab. Vector P is formed based on element by element operation. P= (t^2- squareroot 5)/sin(t) >> P = t^2- squareroot (5)/Sin(t) >> P = (t^2- squareroot (5))/sin(t) >> P= (t.^2- squareroot (5)) ./sin(t) Write a MATLAB statement to generate the variable Z. Here x is a VECTOR. Avoid redundant operators. (x) = 4x^3cos (2x^5-5x) >> = 4* x * 0.3 .* cos(2* x*0. 5 - 5* x) >> = 4* x^3 .* cos(2* x.^5 - 5* x) >> = 4* x.^3 .* cos(2* x.^5 - 5* x) >> =4.* x^3 .* cos(2.* x^5 - 5.* x) How do we create a new directory called \"Projects\" inside the current directory? >> make projects >> mkdir Projects >> make Projects >> pwd Projects How do you list all the folders and files inside the current directory in Matiab? >> what >> Is >> dir >> Both b and c are correct

Solution

Note the concept

. /   --> means pointwise division --> used for vectors

/   --> Simple division --> used for scalar

A = [1 2 3; 3 2 1]

B = A. ^2

Pointwise operator is used in case we have vector, matrix etc.

Question 5:

T is vector so answer will be

P= (t. ^2-sqrt (5)). /sint(t)

Question 6:

4 is scaler so we need 4*

X is vector so x. ^3

So answer will

4*x. ^3.*cos (2*x. ^5-5*x)

Question 7:

>> mkdir Projects is correct option

mkdir – this is make directory command

Question 8:

dir /ls command àLists all files in current directory.

what command àLists all MATLAB files in the current directory.

So both b and c
