Create a row vector named b that starts at 1, ends at 10, and contains 5 elements.

@Balanarayanan This looks like a homework problem. If you have any questions ask your instructor or read the link below to get started:

Obviously we can't give you the full solution because you're not allowed to turn in our code as your own, but it will involve linspace and the ' (apostrophe) symbol.

Answer 1

[DGM]

one way:

x = 1:2.25:10

x = 1×5

1.0000 3.2500 5.5000 7.7500 10.0000

another way

x = linspace(1,10,5) 

x = 1×5

1.0000 3.2500 5.5000 7.7500 10.0000

of course, nothing says the vector had to be linear:

x = logspace(0,1,5) 

x = 1×5

1.0000 1.7783 3.1623 5.6234 10.0000

or monotonically increasing

x = [1 500 -pi sqrt(2) 10]

x = 1×5

1.0000 500.0000 -3.1416 1.4142 10.0000

You learn these basics in the first half hour of the intro MATLAB course. Evidently you need to take this:

Transpose b from a row vector to a column vector using the transpose operator.

[Image Analyst]

b=b'

[Voss]

The transpose operator is .'

' is the complex conjugate transpose operator.

Answer 3

[Meghana]

Create a row vector that has the following elements: , , , , 129, and .

[DGM]

Oh that's easy

a = 129

a = 129

Note that a scalar is both a row vector and a column vector. It's also a matrix.

% yes, it's a row vector
[isscalar(a) isvector(a) isrow(a) iscolumn(a) ismatrix(a)]

ans = 1x5 logical array
   1   1   1   1   1

You probably didn't want that, but you never bothered to actually check to see if what you copy-pasted actually worked.
