    This function returns values along a linear trend. This function fits a straight line to the arrays known x and y values. Trend returns the y values along that line for the array of specified new x values.




    This function has these arguments:

    Argument Description
    y Set of y values that are known in the relationship y=mx+b
    x (Optional) X is an optional set of x values that may be known in the relationship y=mx+b
    newx New x values for which this functions returns the corresponding y values
    constant Logical value that specifies whether to force the constant b to equal 0


    If constant is true or omitted then b is calculated normally. If constant is false then b is equal to 0 and the m values are adjusted so that y=mx.

    If x is omitted then x defaults to the array {1,2,3...}, that has the same dimensions as y.

    If newx is omitted then it defaults to x.

    Use the INDEX function to get individual elements from the returned array.
