Candycrush code

I have to make a simple candycrush-like game code in scilab, I have managed to get elements in a matrix to move to other places, but what can I do to make those items to disappear when 3 of them have the same value, and then make the matrix replace the new free slots in it?

```function candycrush()

a=ceil(rand(8,8)*4)
disp(a)
f=input("Select the row you wish to move: ")
c=input("Select the column you wish to move: ")
m=input("Select the direction you want to move in:")
t=1 //number of turns, maximum of 20//
p=0 //number of points//
if m==1 then
temp=a(f,c)
a(f,c)=a(f-1,c)
a(f-1,c)=temp
t=(t+1)
elseif m==2 then
temp=a(f,c)
a(f,c)=a(f+1,c)
a(f+1,c)=temp
t=(t+1)
elseif m==3 then
temp=a(f,c)
a(f,c)=a(f,c+1)
a(f,c+1)=temp
t=(t+1)
elseif m==4 then
temp=a(f,c)
a(f,c)=a(f,c-1)
a(f,c-1)=temp
t=(t+1)
end
//My question is in this part of the code, when 3 items match, how to make them go and be replaced
if a(f,c)=a(f-2,c) & a(f,c)=a(f-3,c) then
elseif a(f,c)=a(f+2,c) & a(f,c)=a(f+3,c) then
elseif a(f,c)=a(f,c+2) & a(f,c)=a(f,c+3) then
elseif a(f,c)=a(f,c-2) & a(f,c)=a(f,c-3) then
end

//Up=1 Down=2 Right=3 Left=4//
disp(a)
endfunction```

Let us say you have to remove k tiles from row f to f+k from column c and refill it. A function will help here:

``````function removetiles(a,k,f,c)
a(1+k:f+k,c) = a(1:f,c)
for tile=k:-1:1 do
a(tile,c) = rand(8,8)```
`endfunction````

For pure horizontal matching, k will be 1, f will be the row number, and c will be the three column numbers from which you have to remove.

For pure vertical matching, k will be 3, f will be the three row numbers, and c will be the column number from which you have to remove.
