When I type in the following code, the Matlab says it's an undefined function?
>> [Call, Put] = blsprice(100, 95, 0.1, 0.25, 0.5)
??? Undefined function or method 'blsprice' for
input arguments of type 'double'.
But I think 'blsprices' is a function that is in the Financial Toolbox. So is there anybody who can help me with this problem?
Thank you!

Use the ver command to see what toolboxes you have installed. If the financial toolbox is not there, that would explain your problem. If your license permits then you need to install it

If not, then either buy it, write the function yourself or try it in a computer with the toolbox installed.

Also, sometimes documented functions might be newer than the version you have installed.
