SigmoidMatrix:** \n\nImplements the sigmoid activation function to each cell of a matrix of type `[[Decimal]]`.\n\n**Usage:**\n\n```swift\nimport MatrixFlow\nlet matrix: [[Decimal]] = [\n    [1.8, 2.0, 3.0], \n    [4.9, 5.0, 6.0], \n    [7.0, 8.0, 9.0]\n]\n\nlet result: [[Decimal]] = MatrixFlow.sigmoidMatrix(matrix)\n//expected result: [[Decimal]] = [[0.8581489350995122176, 0.880797077977882624, 0.9525741268224335872], [0.9926084586557181952, 0.9933071490757152768, 0.9975273768433655808], [0.9990889488055998464, 0.9996646498695335936, 0.9998766054240137216]]\n```\n\n**5. ConvertMultiArrayToArray:**\n\nThis function is designed to convert an `MLMultiArray` with three dimensions into a 3D matrix ready for use.\n\n**Usage:**\n\n```swift\nimport MatrixFlow\nlet shape: [NSNumber] = [1, 3, 4]\n\nguard let multiArray = try? MLMultiArray(shape: shape, dataType: .float32) else {\n    fatalError(\"Failed to create MLMultiArray\")\n}\n\n// Populate the MLMultiArray\nfor i in 0..<shape[0].intValue {\n    for j in 0..<shape[1].intValue {\n        for k in 0..<shape[2].intValue {\n            let indices = [i, j, k] as [NSNumber]\n            multiArray[indices] = NSNumber(value: i + j + k)\n        }\n    }\n}\nlet result: [[[Decimal]]] = MatrixFlow.convertMultiArrayToArray(multiArray)\n\n// expected result: [[[Decimal]]] = [[[0, 1, 2, 3], [1, 2, 3, 4], [2, 3, 4, 5]]]\n```\n\n---\n\n**6. Transpose:**\n\n\nThis function transposes a 2D matrix, essentially swapping its rows with columns.\n\n**Usage:**\n``` swift\nimport MatrixFlow\nlet array: [[Decimal]] = [[0, 1, 2, 3], [1, 2, 3, 4], [2, 3, 4, 5]]\n\nlet result = MatrixFlow.transpose(array)\n\n//expected result: [[Decimal]] = [[0, 1, 2], [1, 2, 3], [2, 3, 4], [3, 4, 5]]\n```\n\n---\n\n**7. ReshapeArray:**\n\nThis function reshapes a 3D matrix by merging its last two dimensions.\n\n**Usage:**\n\n```swift\nimport MatrixFlow\nlet array: [[[Decimal]]] = [[[1.1, 1.2], [1.3, 1.4], [1.5, 1.6], [1.7, 1.8]], [[2.1, 2.2], [2.3, 2.4], [2.5, 2.6], [2.7, 2.8]], [[3.1, 3.2], [3.3, 3.4], [3.5, 3.6], [3.7, 3.8]]]\n\nlet result = MatrixFlow.reshapeArray(inputArray: array)\n\n//expected result: [[Decimal]] = [[1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8], [2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8], [3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8]]\n```\n\n---\n\n**8. Slice:**\n\nThis function performs matrix slicing. Given a matrix, it retrieves the first five rows.\n\n**Usage:**\n\n```swift\nimport MatrixFlow\nlet input: [[Decimal]] = [[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 50], [11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 15], [21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 16]]\n\n//Specify the start and end index of the slicing\nlet start = 0\nlet end = 5\n\nlet result = MatrixFlow.slice(inputArray: input, start: 0, end: 5)\n\n//expected result: [[Decimal]] = [[1, 2, 3, 4, 5], [11, 12, 13, 14, 15], [21, 22, 23, 24, 25]]\n```\n\n---\n\n**9. CombineMatrix:**\n\nThis function is analogous to the numpy `hstack` operation. It horizontally stacks two matrices.\n\n**Usage:**\n\n```swift\nimport MatrixFlow\n// boxes and masks are named for illustration purposes\nlet arrayA: [[Decimal]] = [[1, 2, 3, 4, 5], [11, 12, 13, 14, 15], [21, 22, 23, 24, 25]]\nlet arrayB: [[Decimal]] = [[6, 7, 8, 9, 10, 50], [16, 17, 18, 19, 20, 15], [26, 27, 28, 29, 30, 16]]\n\nlet result = MatrixFlow.combineMatrix(boxes: arrayA, masks: arrayB)\n\n//expected results: [[Decimal]] = [[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 50], [11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 15], [21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 16]]\n```",
