RELATED IDEAS

Expand Vector Arithmetics

Enhance Vectore calculation beyond VECTOR_COSINE(),TO_VECTOR(),VECTOR_DOT_PRODUCT()

I especially miss these functions:

  • FROM_VECTOR to get the content of $ZV into a variable (JSON ?)

  • ADD_VECTOR() for transformation. For INT and DOUBLE

  • DiFF_VECTOR() for Vector distance For INT and DOUBLE

    I wrote an overview of what is available actually.
    Using VECTORs in ObjectScript
    Almost everything is there already. It just needs to be wrapped into SQL Procedures.
    Not a big deal for an experienced COS developer

    As my replies and comments show it is doable but incredibly uncomfortable
    Some simpler approaches as SQL Methods will be attrative

    ADD_VECTOR:
    >zw vec1,vec2

    vec1={"type":"integer", "count":3, "length":3, "vector":[100,300,678]}  ; <VECTOR>

    vec2={"type":"integer", "count":3, "length":3, "vector":[123,345,678]}  ; <VECTOR>
    >set vplus=$vop("v+",vec1,vec2)

    >zw vplus

    vplus={"type":"integer", "count":3, "length":3, "vector":[223,645,1356]}  ; <VECTOR>

    DIFF_VECTOR:set vdiff=$vop("v-",vec1,vec2)

    USER>zw vdiff

    vdiff={"type":"integer", "count":3, "length":3, "vector":[-23,-45,0]} ; <VECTOR>

    digging across documentation I detected that this is all available in COS!
    and even well described in the documentation.

    $vector()
    $vectorop (ObjectScript)
