How to implement my own sparse matrix functionality in matlab

I am supposed to implement my own sparse matrix functionality for a matlab script. And I am a little uncertain how to proceed with this. I guess the main purpose of having sparse matrices is to use less memory. So storing the matrix coordinates and nonzero values in for example 3 vectors, one for row number, one for column number and one for the value, would possibly use more memory in some cases. So what would be a good way to store those values? Is there some effective way of storing tuples for the coordinates like matlabs built in sparse functionality does?

    In the Tips section of the sparse documentation there's a link to a paper called "Sparse Matrices In MATLAB: Design and Implementation" that might be helpful.

Quarantine

For other uses, see Quarantine (disambiguation). Signal flag "Lima" called the "Yellow Jack" which when flown in harbor means ship is under quarantine. A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection. A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time. [1] This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease. [2] The term is often erroneously used to mean medical isolation, which is "to separate ill persons who have a communicable disease from those who are healthy
