This class extends `Float32Array` to provide an efficient way to create and manipulate a 2x2 matrix. Various convenience methods are provided for common matrix operations. ## Constructors <table><thead><tr><th> Constructor </th><th> Modifiers </th><th> Description </th></tr></thead> <tbody><tr><td> [(constructor)(m00, m01, m10, m11)](./server.matrix2._constructor_.md) </td><td> </td><td> Constructs a new instance of the `Matrix2` class </td></tr> </tbody></table> ## Properties <table><thead><tr><th> Property </th><th> Modifiers </th><th> Type </th><th> Description </th></tr></thead> <tbody><tr><td> [determinant](./server.matrix2.determinant.md) </td><td> `readonly` </td><td> number </td><td> The determinant of the matrix. </td></tr> <tr><td> [frobeniusNorm](./server.matrix2.frobeniusnorm.md) </td><td> `readonly` </td><td> number </td><td> The frobenius normal of the matrix. </td></tr> </tbody></table> ## Methods <table><thead><tr><th> Method </th><th> Modifiers </th><th> Description </th></tr></thead> <tbody><tr><td> [add(matrix2)](./server.matrix2.add.md) </td><td> </td><td> Adds a matrix to the current matrix. </td></tr> <tr><td> [adjoint()](./server.matrix2.adjoint.md) </td><td> </td><td> Sets the adjugate of the current matrix. </td></tr> <tr><td> [clone()](./server.matrix2.clone.md) </td><td> </td><td> Clones the current matrix. </td></tr> <tr><td> [copy(matrix2)](./server.matrix2.copy.md) </td><td> </td><td> Copies a matrix to the current matrix. </td></tr> <tr><td> [create()](./server.matrix2.create.md) </td><td> `static` </td><td> Creates a new `Matrix2` instance. </td></tr> <tr><td> [equals(matrix2)](./server.matrix2.equals.md) </td><td> </td><td> Checks if the current matrix is approximately equal to another matrix. </td></tr> <tr><td> [exactEquals(matrix2)](./server.matrix2.exactequals.md) </td><td> </td><td> Checks if the current matrix is exactly equal to another matrix. </td></tr> <tr><td> [fromRotation(angle)](./server.matrix2.fromrotation.md) </td><td> `static` </td><td> Creates a new `Matrix2` instance from a rotation of identity matrix. </td></tr> <tr><td> [fromScaling(scale)](./server.matrix2.fromscaling.md) </td><td> `static` </td><td> Creates a new `Matrix2` instance from a scale of identity matrix. </td></tr> <tr><td> [identity()](./server.matrix2.identity.md) </td><td> </td><td> Sets the current matrix to the identity matrix. </td></tr> <tr><td> [invert()](./server.matrix2.invert.md) </td><td> </td><td> Inverts the current matrix. </td></tr> <tr><td> [multiply(matrix2)](./server.matrix2.multiply.md) </td><td> </td><td> Multiplies the current matrix by another matrix. </td></tr> <tr><td> [multiplyScalar(scalar)](./server.matrix2.multiplyscalar.md) </td><td> </td><td> Multiplies each element of the current matrix by a scalar value. </td></tr> <tr><td> [rotate(angle)](./server.matrix2.rotate.md) </td><td> </td><td> Rotates the current matrix by an angle in radians. </td></tr> <tr><td> [subtract(matrix2)](./server.matrix2.subtract.md) </td><td> </td><td> Subtracts a matrix from the current matrix. </td></tr> <tr><td> [toString()](./server.matrix2.tostring.md) </td><td> </td><td> Returns a string representation of the current matrix. </td></tr> <tr><td> [transpose()](./server.matrix2.transpose.md) </td><td> </td><td> Transposes the current matrix. </td></tr> </tbody></table>
