setMatrixX0 :: MonadIO m => Matrix -> Double -> m ()gi-pango GI.Pango.Structs.Matrix Set the value of the “x0” field. When overloading is enabled, this is equivalent to
set matrix [ #x0 := value ]
setMatrixXx :: MonadIO m => Matrix -> Double -> m ()gi-pango GI.Pango.Structs.Matrix Set the value of the “xx” field. When overloading is enabled, this is equivalent to
set matrix [ #xx := value ]
setMatrixXy :: MonadIO m => Matrix -> Double -> m ()gi-pango GI.Pango.Structs.Matrix Set the value of the “xy” field. When overloading is enabled, this is equivalent to
set matrix [ #xy := value ]
setMatrixY0 :: MonadIO m => Matrix -> Double -> m ()gi-pango GI.Pango.Structs.Matrix Set the value of the “y0” field. When overloading is enabled, this is equivalent to
set matrix [ #y0 := value ]
setMatrixYx :: MonadIO m => Matrix -> Double -> m ()gi-pango GI.Pango.Structs.Matrix Set the value of the “yx” field. When overloading is enabled, this is equivalent to
set matrix [ #yx := value ]
setMatrixYy :: MonadIO m => Matrix -> Double -> m ()gi-pango GI.Pango.Structs.Matrix Set the value of the “yy” field. When overloading is enabled, this is equivalent to
set matrix [ #yy := value ]
tabArrayGetPositionsInPixels :: (HasCallStack, MonadIO m) => TabArray -> m Boolgi-pango GI.Pango.Structs.TabArray Returns True if the tab positions are in pixels, False if they are in Pango units.
tabArraySetPositionsInPixels :: (HasCallStack, MonadIO m) => TabArray -> Bool -> m ()gi-pango GI.Pango.Structs.TabArray Sets whether positions in this array are specified in pixels. Since: 1.50
windowUnrollIx2 :: Window ix e -> !Maybe Intmassiv Data.Massiv.Array.Delayed Setting this value during stencil application improves cache utilization by unrolling the loop for Ix2 and higher dimensions. Has no affect on arrays with one dimension.
identityMatrix :: Num e => Sz1 -> Matrix DL emassiv Data.Massiv.Array.Numeric Create an indentity matrix.
Example
>>> import Data.Massiv.Array >>> identityMatrix 5 Array DL Seq (Sz (5 :. 5)) [ [ 1, 0, 0, 0, 0 ] , [ 0, 1, 0, 0, 0 ] , [ 0, 0, 1, 0, 0 ] , [ 0, 0, 0, 1, 0 ] , [ 0, 0, 0, 0, 1 ] ]
