What does the line of code below return? Your GUI is expecting a function with the name plotchar. Do you actually have it?

which plotchar -all

I deleted the flag because the question is perfectly clear to me.

Answer 1

[per isakson]

The error message states that the function plotchar isn't found.

>> plotchar
'plotchar' requires Character Recognition Example. 
>> which plotchar -all
<snip>\Documents\MATLAB\Examples\nnet\appcr1\plotchar.m
>> 

Possible measures

• add <snip>\Documents\MATLAB\Examples\nnet\appcr1\plotchar.m to the path.
• make a copy of plotchar with a slighly different name, e.g. plotchar2, and replace plotchar by plotchar2 in charGUI10.m. I would have done that to avoid messing with the examples.

Got the point. I don't have plotchar.m file. Now how can i create a plotchar.m file to run the feature extract button? i need to recognize habdwritten numbers.

Did you try to reproduce the commands I showed in my answer?

Did you try anything of Possible measures ?

[NAWSHIN MANNAN PROMA]

yes, i tried but it didn't work,i got the same error.

[per isakson]

How do you think that I should know what you tried and in what way it didn't work ???

Two questions: What does

>> plotchar

return? And what does

>> which plotchar -all

return?
