Undefined function or variable 'Store5'.

Error in Untitled5 (line 108)
Store = [Store1;Store2;Store3;Store4;Store5;Store6];

For the store line, it only work up to Store4....I don't know how to fix the error. This code is working under the boolean algebra toolbox V2.2 environment.

Answer 1

[surabhi]

Use the debugger, and see where and why it gives an error at Store5. May be its not getting the inputs for calculating Store5.

Answer 2

[Walter Roberson]

Each of your Store* variables is not initialized, and is only set conditionally. If that condition is not satisfied then the Store* variable will never have been given a value.

You should be asking yourself why you create the Temp1 and Temp2 variables for all the cases but only use them for the Store1 case.

You should be asking yourself why you have "clear all" in a program. It does not do whatever-it-is that you are thinking that it does. If you are trying to ensure that the values of variables are not present in memory then use a function instead of a script.

You should be asking yourself why you do not have comments in the code.

there is a code that given by the prof and then this is my code that modify from the given one...the origin code has 4 stores only...but now I need 6 inputs with 6 stores... For the temp1 is Search for change in each input and corresponding change in output while other inputs remain constant...The final store is store each test vector in a MATRIX....It works for the original code...

[Walter Roberson]

Your loops run to 16, which is 2^4, suitable for taking each possible combination of 4 binary values. But now you are dealing with 6 binary values so running your loops to 16 is not appropriate.

thx man...I got it....
