Function getMatrixDataType #
Find the data type of all elements in a matrix or array, for example ‘number’ if all items are a number and ‘Complex’ if all values are complex numbers. If a matrix contains more than one data type, it will return ‘mixed’.
Syntax #
math.getMatrixDataType(x)
Parameters #
| Parameter | Type | Description |
|---|---|---|
x |
…Matrix | Array | The Matrix with values. |
Returns #
| Type | Description |
|---|---|
| string | A string representation of the matrix type |

Examples #
const x = [ [1, 2, 3], [4, 5, 6] ]
const mixedX = [ [1, true], [2, 3] ]
const fractionX = [ [math.fraction(1, 3)], [math.fraction(1, 3)] ]
const unitX = [ [math.unit('5cm')], [math.unit('5cm')] ]
const bigNumberX = [ [math.bignumber(1)], [math.bignumber(0)] ]
const sparse = math.sparse(x)
const dense = math.matrix(x)
math.getMatrixDataType(x) // returns 'number'
math.getMatrixDataType(sparse) // returns 'number'
math.getMatrixDataType(dense) // returns 'number'
math.getMatrixDataType(mixedX) // returns 'mixed'
math.getMatrixDataType(fractionX) // returns 'Fraction'
math.getMatrixDataType(unitX) // returns 'Unit'
math.getMatrixDataType(bigNumberX) // return 'BigNumber'
