Maximum Value inside an array

Is there a function that gets the maximul value insinde an Array:

For example:

doublearray weights = makearray(3);
fillarray(weights, 3.5, 6.7, 1.4);

max(weights) => returns 6.7

Congshi,

this should give you an idea, how to implement the maximum value search. Make it a user command, if you need it at various locations within your model:

doublearray weights=makearray(5); // DEFINE ARRAY
for (int i=1; i<=5; i ++) // FILL ARRAY WITH RANDOM VALUES
{
weights[i]=uniform(1,10);
pf(weights[i]);pr(); // PRINT ALL VALUES TO OUTPUT CONSOLE
}
double maxweight=0; // VARIABLE FOR MAX WEIGHT IN ARRAY
for (int j=1; j<=5; j ++) // LOOK THROUGH ALL ARRAY VALUES
{
if(weights[j]>maxweight) // CHECK IF ARRAY CVALUE IS LARGER THAN CURRENT MAX VALUE
{
maxweight=weights[j]; // IF SO, SET NEW MAX VALUE TO CURRENT ARRAY VALUE
}
}
pt("Max weight: ");pf(maxweight);pr();pr(); // PRINT MAX FOUND VALUE TO OUTPUT CONSOL
return maxweight; // RETUNR MAX FOUND VALUE

Hope that helps!

Hello

Is there a command to create a multi dimensional array ??

Thanks

Nischith,

No there is no multi dimensional array command in Flexsim.

However, I was told by someone who knows what there talking about, that all arrays are stored in memory the same way as single dimensional arrays and that the only difference between a multi and a single was who was doing the work. Confused yet?

Here is an example of two arrays that are for all intents and purposes exactly the same (C++):

int rows = 10;
int cols = 5;
double arrayone[rows, cols];
double arraytwo[rows * cols];
int count = 0;
for(int row = 0; row < 10; row++){
  for(int col = 0; col < 5; col++){
    count++;
    arrayone[row, col] = count;
    arraytwo[(row * cols) + col] = count;
  }
}

I hope that this example helps you get the idea I'm trying to portray.

So, what do you care? Here is how I would use an array in Flexscript to hold two dimensional data:

int rows = 10;
int cols = 5;
intarray test = makearray(rows*cols);
int row;
int col;
int count = 0;
for(row = 1; row <= 10; row++){
  for(col = 1; col <= 5; col++){
    count++;
    test[((row - 1) * cols) + col] = count;
  }
}
for(row = 1; row <= 10; row++){
  for(col = 1; col <= 5; col++){
  	pr(); pd(test[((row - 1) * cols) + col]);
  }
}

I hope that this long winded explanation helps,
Brandon

Along the same lines as Brandon's response, if you want to get really funky, then you can use #defines to make a crazy syntax for multdimentional arrays to use arrayname[ROW 4 COL 7] as the syntax for referencing the array.

The following code shows how this can be done.

int sizex = 15;
int sizey = 4;
doublearray test = makearray(sizex*sizey);
#define ROW sizey*(
#define COL -1)+
int num = 1;
for(int x=1;x<=sizex;x++)
{
    for(int y=1;y<=sizey;y++)
    {
        test[ROW x COL y] = num;
        num++;
        pt("row: ");pd(x);
        pt(" col: ");pd(y);
        pt(" is: ");
        pd(test[ROW x COL y]);pr();
    }
}
