Algorithm (Workflow)
This function, randminv, generates a random matrix with specified dimensions and a minimum value. It is part of the SolidGeometry library and was introduced in version 4.4.
Input Parameters
- r: Number of rows in the output matrix.
- c: Number of columns in the output matrix.
- rmin: A scalar or a two-element vector specifying the minimum value or range [rmin, rmax] for the random values. The default range is [rmin, 1].
Output
- r: A random matrix with dimensions specified by the input parameters and values within the specified range.
Algorithm Steps
- Check the number of input arguments using
nargin. If only one argument is provided, set varargin{1} to r, and default r and c to 1.
- Retrieve the minimum value or range using
getfuncparams with a default of 0 if not specified.
- If
rmin is a scalar, convert it to a two-element vector [rmin, 1].
- Generate a random matrix
r with dimensions (r, c) using the rand function.
- Scale and shift the random values to fit within the specified range
[rmin(1), rmin(2)] using the formula: r = r * (rmin(2) - rmin(1)) + rmin(1).
