Insufficient number of outputs from right hand side of equal sign to satisfy assignment.

this is my code, when i run the second line it is showing the above error , what is the procedure to rectify it.

picture2=double(picture2);
[Left_V,Right_V]=validate(picture2);
 Left_V = Left_V*0.026;
 Right_V = Right_V*0.026;
 bb=Left_V/Right_V;
fprintf('Pixels in Centimeter(Right_V) %0.03f',Right_V);
fprintf('Pixels in Centimeter (Left_V) %0.03f',Left_V);
fprintf('LV/RV ratio is %0.03f',bb)

What is validate? I suspect it might be a variable rather than a function

[Ragini Narasimha]

yes but i am not able to define it either

Answer 1

[Walter Roberson]

[Left_V, Right_V] = deal( validate(picture2) );

[Ragini Narasimha]

Undefined function 'validate' for input arguments of type 'double'. this is the error that is displaying when i tried this

[madhan ravi]

which validate -all % what does this show?

[Walter Roberson]

What do you think that validate() does? Is it possibly part of a third-party software package?

[Ragini Narasimha]

i am not sure as when i ran validate on the matlab doci did not arrive at any answer

[Ragini Narasimha]

which validate -all % what does this show?

it says its an invalid expression when i gave the above syntax

[Walter Roberson]

Which MATLAB release are you using?
