ADD

Download Flojoy Studio to try this app

Add two or more numeric arrays, matrices, dataframes, or constants element-wise. When a constant is added to an array or matrix, each element in the array or matrix will be increased by the constant value. If two arrays or matrices of different sizes are added, the output will be the size of the larger array or matrix with only the overlapping elements changed. Params: a : OrderedPair|Scalar|Vector The input a use to compute the sum of a and b. b : OrderedPair|Scalar|Vector The input b use to compute the sum of a and b. Returns: out : OrderedPair|Scalar|Vector OrderedPair if a is an OrderedPair. x: the x-axis of input a. y: the sum of input a and input b. Scalar if a is a Scalar. c: the sum of input a and input b. Vector if a is a Vector. v: the sum of input a and input b.

In this example, LINSPACE generates an array from 0 to 10 that has a length of 1000.

This array is then passed to the SINE nodes, which compute numpy.sine(). They are added through ADD node and the output is visualized through SCATTER node.
