okay thanks i will change the statement also this is the full error code
Index in position 1 exceeds array bounds (must not exceed 1).
Error in c1/evaluate (line 218)
if a(j,k) == a(2,2)
Error in c1 (line 416)
scorecard(j,3) = evaluate(AA,BB,CC,DD,EE,FF)
i think the problem comes from the variables it is acting on is defined in a nested function so it cant access it but i dont know how to fix this

Edited: DGM on 3 May 2022
Since I don't even know how to call the function or what it's supposed to do, I can't really do much but point out problems and hope those are the only ones and that you'll know how to translate that evidence into a solution.
It's not an issue of access to a variable in some other scope. You're trying to access a(2,2), but a has only one row so there is no such element. Where did a come from?
function [score] = evaluate(a,b,c,d,e,f)
It was passed as an input argument. So what was it in the calling scope?
scorecard(j,3) = evaluate(AA,BB,CC,DD,EE,FF)
It was AA. You might be expecting AA to be a 3x3 matrix, but there's a couple problems.
AA = [0,0,0:0,0,0:0,0,0]
That's not a 3x3 matrix. That's a 1x7 vector. You probably meant to write
AA = [0,0,0;0,0,0;0,0,0]; % terminate lines with semicolon
That would cause the error.
Even if you change that, you'll probably still have the same error because of what precedes the call to evaluate():
% ...
moves(scorecard(j,1),white,red,green,orange,blue,yellow) % this does nothing
moves(scorecard(j,2),AA,BB,CC,DD,EE,FF) % this does nothing
scorecard(j,3) = evaluate(AA,BB,CC,DD,EE,FF)
% ...
The outputs from both calls to move() are unused.
If they were being used, then AA would be scalar instead of 3x3 or 1x7 or whatever. Why? Well, the output of moves() is ostensibly AA,BB, etc. So AA would ostentibly change. What would it change to?
function [AA,BB,CC,DD,EE,FF] = moves(move,a,b,c,d,e,f)
if move == 1
clockwise(a,b,c,d,e,f)
AA = t1 % t1 is a scalar
BB = t2
CC = t3
DD = t4
EE = t5
FF = t6
elseif move == 2
% ...
end
% ...
end
It would change to t1, which is one of the scalar input arguments to the main function.
function [white,red,green,orange,yellow,movie] = c1(f1,f2,f3,f4,f5,f6,f7,f8,f9,t1,t2,t3,t4,t5,t6,t7,t8,t9,r1,r2,r3,r4,r5,r6,r7,r8,r9,u1,u2,u3,u4,u5,u6,u7,u8,u9,l1,l2,l3,l4,l5,l6,l7,l8,l9,b1,b2,b3,b4,b5,b6,b7,b8,b9)
... but you probably expect t1 to be a 3x3 matrix because of that call to clockwise() right above it. After all, clockwise() takes that pile of named scalars and makes a pile of matrices, confusing everything by reusing variable names for different things.
function [t1,t2,t3,t4,t5,t6] = clockwise(a1,a2,a3,a4,a5,a6)
t1 = [a1(3,1),a1(2,1),a1(1,1);a1(3,2),a1(2,2),a1(1,2);a1(3,3),a1(2,3),a1(1,3)]
t2 = a2
t2(1,:) = a3(1,:)
t3 = a3
t3(1,:) = a4(1,:)
t4 = a4
t4(1,:) = a5(1,:)
t5 = a5
t5(1,:) = a2(1,:)
t6 = a6
end
Well, that might be what clockwise() is supposed to do, but its outputs are unused. So the call to clockwise() doesn't change the input argument t1 to an unrelated 3x3 matrix of the same name, so AA will be the scalar t1 that was passed to the main function.
Do with that what you will.
With a conceptual or diagrammatic explanation of the intended behavior, this could possibly be rewritten with less group effort than it would take to debug it completely and with confidence.
DGM on 3 May 2022
I'm going to throw this out there. Maybe you're expecting the variables to be shared between functions since they're nested, and maybe that's why you're not assigning the output of your function calls.
If so, then the way you're defining the functions is breaking that variable sharing. When you do this:
function [AA,BB,CC,DD,EE,FF] = moves(move,a,b,c,d,e,f)
you're creating new variables AA,BB, etc which exist only within the scope of this function. In order to share the same AA, etc that are used in the main function scope, don't define them anew in the nested function.
function moves(move,a,b,c,d,e,f)
I attached a copy with some edits. It almost certainly doesn't work yet, but you should see that those variables have changed color because they're being shared.
