Evaluating a string, MATLAB in Engineering

Assignment Help:

Evaluating a string:

The function eval is used to compute a string as a function. For illustration, below is the string 'plot(x)'is interpreted to be a call to plot the function, and it generates the plot as shown in figure.

>> x = [2 6 8 3];

>> eval('plot(x)')

This would be helpful if the user entered the name of the type of plot to use. In illustration, the string that user enters (in this situation 'bar') is concatenated with the string '(x)' to generate the string 'bar(x)'; this is then computed as a call to the bar function as shown in figure.

Also, the name of the plot type is used in the title.
