-Welcome.
-
-This spoken tutorial is a self-assessment tutorial and you will be
-able to assess yourself on the concepts learnt in the Module on Arrays
-and Matrices.
-
-
-As with all other assessments we will first start with a few short
-questions that will not take you more that 15 to 20 seconds to
-answer. Then we shall move on to a bigger problem, that you are
-expected to solve in less than 10 mins.
-
-
- * Given a list of marks::
-
- marks = [10, 20, 30, 50, 55, 75, 83]
-
- How will you convert it to an array?
-
- * What is the shape of the following array?::
-
- x = array([[1,2,3,4],
- [3,4,2,5]])
-
- * What is the resulting array::
-
- a = array([[1, 2],
- [3, 4]])
-
- a[1,0] = 0
-
- * What is the resulting array?::
-
- x = array(([1,2,3,4],
- [2,3,4,5]))
-
- x[-2][-3] = 4
-
-
- * How do we change the array ``x = array([[1,2,3,4]])`` to
- ``array([[1,2,0,4]])``?
-
- * How do we get the slice::
-
- array([[2,3],
- [4,2]])
-
- out of the array::
-
- x = array([[1,2,3,4],
- [3,4,2,5]])
-
-
- * What is the output of x[::3,::3], when x is::
-
- x = array([[9,18,27],
- [30,60,90],
- [14,7,1]])
-
- * How do you get the transpose of this array?::
-
- a = array([[1, 2],
- [3, 4]])
-
- * What is the output of the following?::
-
- a = array([[1, 2],
- [3, 4]])
-
- b = array([[1, 1],
- [2, 2]])
-
- a*b

-
-Now, let us move on to a larger problem. From the image
-`tagore-einstein.png``
-
- + extract the face of Einstein alone.
- + extract the face of Tagore alone.
- + get a smaller copy of the image, that is a fourth it's size.
