Is it possible to copy values from two dimension array's row to one dimension array easily?

jeppe · February 2019

Hi,

For simplified example, there's two arrays:

array1{3,3}:=[[1,2,3],[4,5,6],[7,8,9]];

array2{3};

Is it possible to copy values from array1, lets say row 2, to array2 easily? Only way to do this which i've found so far is doing it one value at a time:

array2{1}:=array1{2,1};
array2{2}:=array1{2,2};
array2{3}:=array1{2,3};

doing it one by one isn't really an option with my full scale project

Thanks for help!

FOR loop through and write to the new array?

Here's a basic example:

MODULE mArrayLoopExample

    CONST num array1{3,3}:=[[1,2,3],[4,5,6],[7,8,9]];

    PERS num array2{3}:=[0,0,0];

    PROC ArrayLoopExample()

        FOR i FROM 1 TO Dim(array1,2) DO
            array2{i}:=array1{2,i};
        ENDFOR

    ENDPROC

ENDMODULE

Taking the example a little further:

MODULE mArrayLoopExample

    CONST num array1{3,3}:=[[1,2,3],[4,5,6],[7,8,9]];

    PERS num array2{3}:=[0,0,0];

    PROC ArrayLoopExampleCall()
        ArrayLoopExample array1, array2;
    ENDPROC

    PROC ArrayLoopExample(num InputArray{*,*}, INOUT num OutputArray{*})
        FOR i FROM 1 TO Dim(InputArray,2) DO
            OutputArray{i}:=InputArray{2,i};
        ENDFOR
    ENDPROC

ENDMODULE

Thanks soup, i'll probably use your second example's idea in my project.

No problem! Good luck!

Someone asked privately -- here's a loop within a loop example:

MODULE mArrayLoopExample

    CONST num In1{5,3}:=[[1,2,3],[4,5,6],[7,8,9],[10,11,12],[13,14,15]];

    PERS num Out1{3}:=[0,0,0];
    PERS num Out2{3}:=[0,0,0];
    PERS num Out3{3}:=[0,0,0];
    PERS num Out4{3}:=[0,0,0];
    PERS num Out5{3}:=[0,0,0];

    PROC ArrayMain()
        ArrayLoop In1, "Out";
        Stop;
        ArrayZero In1, "Out";
    ENDPROC

    PROC ArrayLoop(num InputArray{*,*}, string OutputArrayName)
        VAR num tempArray{3};
        FOR j FROM 1 TO Dim(InputArray,1) DO
            GetDataVal OutputArrayName+NumToStr(j,0),tempArray;
            FOR i FROM 1 TO Dim(InputArray,2) DO
                tempArray{i}:=InputArray{j,i};
            ENDFOR
            SetDataVal OutputArrayName+NumToStr(j,0),tempArray;
        ENDFOR
    ENDPROC

    PROC ArrayZero(num InputArray{*,*}, string OutputArrayName)
        VAR num tempArray{3};
        FOR j FROM 1 TO Dim(InputArray,2) DO
            tempArray{j}:=0;
        ENDFOR
        FOR j FROM 1 TO Dim(InputArray,1) DO
            SetDataVal OutputArrayName+NumToStr(j,0),tempArray;
        ENDFOR
    ENDPROC

ENDMODULE
