ones

Builtin index · Core maths

result = ones(n) / ones(r, c)

Input: n · Output: result

What it is

A vector or matrix of ones, with the same one-argument-vs-two-argument shape rules as zeros above.

Overloads

One call shape — this function is not overloaded.

Code	Input	Output	Description
`result = ones(n) / ones(r, c)`	`n` vector or matrixnot documented yet	`result` Vec or Mat	Returns a length-`n` `Vec` for `ones(n)`, or an `r×c` `Mat` for `ones(r, c)`.

Examples

From the documentation, and run by the build -- the output and the figure below are what the engine actually produced. Simplest first.

idx = 0 to 100
theta = idx ./ 100 .* (2*pi)
r = ones(101)
polarplot(theta, r)   # a unit circle, drawn as an (x, y) curve
