# randgenMatrix-npm-pakcage (under development) ## randgenMatrix Generate array or matrix of random number with specified range, size, decimal, and export to txt or csv file. ## Installation > npm install randgenmatrix ## Usage ### GenerateRandomArray Generate an array of random number. `min` and `max` specifies the range, `length` specifies the number of elements, `decimal` specifies the number of digits to be saved after decimal point. > GenerateRandomArray(length, min, max, decimal) Example: > GenerateRandomCol(7, 56, 80, 2) Returns: > (7) ['79.11', '67.02', '65.51', '70.45', '75.17', '76.71', '62.92'] ### GenerateRandomMatrix Generate an array of random number. `min` and `max` specifies the range, `rows` specifies the number of elements in a row, `cols` specifies the number of elements in a cols, `decimal` specifies the number of digits to be saved after decimal point. > GenerateRandomMatrix(rows, cols, min, max, decimal) Example: > GenerateRandomMatrix(7, 3, 56, 80, 2) Returns: > [Array(3), Array(3), Array(3), Array(3), Array(3), Array(3), Array(3)] Each array is a row. > console.log(GenerateRandomMatrix(7, 3, 56, 80, 2)[0]) Access the first row. Returns: > (3) ['64.75', '64.67', '64.01'] ### GenerateArrayByPattern Example: Returns: ### ExportRandomRow > ExportRandomRow(length, min, max, decimal, exportType, exportPath) Example: Returns: ### ExportRandomCol Example: Returns: ### ExportRandomMatrix Example: Returns: ### ExportArrayByPattern Example: Returns:
