Vector Addition

Function Prototype

/* Vector Addition */
/* Type: simple */
/* Input arrays: 2    Options: 0    Output arrays: 1 */
/* Inputs: real, real */
/* Options: none */
/* Outputs: add */
int ti_add_start(TI_REAL const *options);
int ti_add(int size,
      TI_REAL const *const *inputs,
      TI_REAL const *options,
      TI_REAL *const *outputs);

Description

This documentation is still a work in progress. It has omissions, and it probably has errors too. If you see any issues, or have any general feedback, please get in touch.

Add simply takes two input arrays and adds them together.

This is sometimes useful as a building block to more complex functions.

Example Usage

Calling From C

/* Example usage of Vector Addition */
/* Assuming that 'input1' and 'input2' are pre-loaded arrays of size 'in_size'. */
TI_REAL *inputs[] = {input1, input2};
TI_REAL options[] = {}; /* No options */
TI_REAL *outputs[1]; /* add */

/* Determine how large the output size is for our options. */
const int out_size = in_size - ti_add_start(options);

/* Allocate memory for output. */
outputs[0] = malloc(sizeof(TI_REAL) * out_size); assert(outputs[0] != 0); /* add */

/* Run the actual calculation. */
const int ret = ti_add(in_size, inputs, options, outputs);
assert(ret == TI_OKAY);

Calling From Lua (with Tulip Chart bindings)

-- Example usage of Vector Addition
add = ti.add(input1, input2)
