Write a script that will first initialize a string variable

Write a script that will first initialize a string variable that will store x and y coordinates of a point in the form \'x 3.1 y 6.4\'. Then, use string manipulating functions to extract the coordinates and plot them.

Solution

a=input(\'Enter the X-coordinate:\');

b=input(\'Enter the Y-coordinate:\');

coord =\'x %.1f y%.1f\';

str = sprintf(coord,a,b);

nums=sscanf(str,\'%*s%f%*s%f\');

plot(nums(1),nums(2),o);

xlabel(\'X Coordinate\');

ylabel(\'Y Coordinate\');
