mat4.perspectiveFromFieldOfView fov wrong type

 * @param {mat4} out mat4 frustum matrix will be written into
 * @param {number} fov Object containing the following values: upDegrees, downDegrees, leftDegrees, rightDegrees
 * @param {number} near Near bound of the frustum
 * @param {number} far Far bound of the frustum

mat4.perspectiveFromFieldOfView = function (out, fov, near, far) {
    var upTan = Math.tan(fov.upDegrees * Math.PI/180.0),
        downTan = Math.tan(fov.downDegrees * Math.PI/180.0),
        leftTan = Math.tan(fov.leftDegrees * Math.PI/180.0),
        rightTan = Math.tan(fov.rightDegrees * Math.PI/180.0),
        xScale = 2.0 / (leftTan + rightTan),
        yScale = 2.0 / (upTan + downTan);

{number} fov Object containing the following values: upDegrees, downDegrees - number is not object =)

Need make object fov.

Same bug and in gl-matrix.d.ts =(

Fixed. Thanks for pointing that out.
