Matrix inverse

Return to the Math APIs page.

After ...herokuapp.com above you should type /api/ and then your (square) matrix.
Spaces are allowed - but discouraged - in whichever format you use, because %20 will replace each space after you hit return, thereby making the address uglier.
Input your matrix (A) as a comma-separated list of comma-separated lists of numbers, each list contained by square brackets.
Represent each number may as an integer or decimal but not as fraction, because "/" has special meaning in a URL. Do not include a comma in any number (even one exceeding one thousand), because that will get confused with the commas which separate different numbers.
example of a 2x2 matrix:
/[[1,2],[3,4]]
If you want to solve a matrix equation of the form Ax = b, then after your matrix type "/" followed by one or more column vectors (b), formatted in the same way as for your square matrix.
example of 3 different systems of equations, each having the same square matrix A (which is the same as in the example above):
/[[1,2],[3,4]]/[[3,5],[2,4],[-1,0]]
If you want the response in html rather than in json, simply omit /api from the address.
