Dear Unix Gurus,
I have a sample data set that looks like this
y1 y2 y3 y4 y5
x1 0.3 0.5 2.3 3.1 5.1
x2 1.2 4.1 3.5 1.7 1.2
x3 3.1 2.1 1.0 4.1 2.1
x4 5.0 4.0 6.0 7.0 1.1
I want to open it up so that I get
x1 y1 0.3
x2 y1 1.2
x3 y1 3.1
x4 y1 5.0
x1 y2 0.5

Hello!
I'm new to linux programming. It would be great if you could help me out.
I have a matrix of kind:
10 30.0
20 190.5
40 180.
50 320.5
I would like
to substract 180 from column 2 If the value is >180
to add 180 for column 2 If the value is <180
nothing if it is equal to... (3 Replies)
Hello all,
I am quite new in this but I need some help to keep going with my analysis.
I am struggling with a short script to read a square matrix and convert it in two collumns.
A B C D

MPSMatrixDescriptor(3) MetalPerformanceShaders.framework MPSMatrixDescriptor(3)NAME
MPSMatrixDescriptor
SYNOPSIS
#import <MPSMatrixTypes.h>
Inherits NSObject.
Class Methods
(__nonnull instancetype) + matrixDescriptorWithDimensions:columns:rowBytes:dataType:
(__nonnull instancetype) + matrixDescriptorWithRows:columns:rowBytes:dataType:
(__nonnull instancetype) + matrixDescriptorWithRows:columns:matrices:rowBytes:matrixBytes:dataType:
(size_t) + rowBytesFromColumns:dataType:
(size_t) + rowBytesForColumns:dataType:
Properties
NSUInteger rows
NSUInteger columns
NSUInteger matrices
MPSDataType dataType
NSUInteger rowBytes
NSUInteger matrixBytes
Detailed Description
This depends on Metal.framework
A MPSMatrixDescriptor describes the sizes, strides, and data type of a an array of 2-dimensional matrices. All storage is assumed to be in
'matrix-major'. See the description for MPSMatrix for further details.
Method Documentation
+ (__nonnull instancetype) matrixDescriptorWithDimensions: (NSUInteger) rows(NSUInteger) columns(NSUInteger) rowBytes(MPSDataType) dataType
Create a MPSMatrixDescriptor with the specified dimensions and data type.
Parameters:
rows The number of rows of the matrix.
columns The number of columns of the matrix.
rowBytes The number of bytes between starting elements of consecutive rows. Must be a multiple of the element size.
dataType The type of the data to be stored in the matrix.
For performance considerations the optimal row stride may not necessarily be equal to the number of columns in the matrix. The MPSMatrix
class provides a method which may be used to determine this value, see the rowBytesForColumns API in the MPSMatrix class. The number of
matrices described is initialized to 1.
+ (__nonnull instancetype) matrixDescriptorWithRows: (NSUInteger) rows(NSUInteger) columns(NSUInteger) matrices(NSUInteger)
rowBytes(NSUInteger) matrixBytes(MPSDataType) dataType
Create a MPSMatrixDescriptor with the specified dimensions and data type.
Parameters:
rows The number of rows of a single matrix.
columns The number of columns of a single matrix.
matrices The number of matrices in the MPSMatrix object.
rowBytes The number of bytes between starting elements of consecutive rows. Must be a multiple of the element size.
matrixBytes The number of bytes between starting elements of consecutive matrices. Must be a multiple of rowBytes.
dataType The type of the data to be stored in the matrix.
For performance considerations the optimal row stride may not necessarily be equal to the number of columns in the matrix. The MPSMatrix
class provides a method which may be used to determine this value, see the rowBytesForColumns API in the MPSMatrix class.
+ (__nonnull instancetype) matrixDescriptorWithRows: (NSUInteger) rows(NSUInteger) columns(NSUInteger) rowBytes(MPSDataType) dataType
+ (size_t) rowBytesForColumns: (NSUInteger) columns(MPSDataType) dataType
+ (size_t) rowBytesFromColumns: (NSUInteger) columns(MPSDataType) dataType
Return the recommended row stride, in bytes, for a given number of columns.
Parameters:
columns The number of columns in the matrix for which the recommended row stride, in bytes, is to be determined.
dataType The type of matrix data values.
To achieve best performance the optimal stride between rows of a matrix is not necessarily equivalent to the number of columns. This method
returns the row stride, in bytes, which gives best performance for a given number of columns. Using this row stride to construct your array
is recommended, but not required (provided that the stride used is still large enough to allocate a full row of data).
Property Documentation
- columns [read], [write], [nonatomic], [assign]
The number of columns in a matrix.
- dataType [read], [write], [nonatomic], [assign]
The type of the data which makes up the values of the matrix.
- matrices [read], [nonatomic], [assign]
The number of matrices.
- matrixBytes [read], [nonatomic], [assign]
The stride, in bytes, between corresponding elements of consecutive matrices. Must be a multiple of rowBytes.
- rowBytes [read], [write], [nonatomic], [assign]
The stride, in bytes, between corresponding elements of consecutive rows. Must be a multiple of the element size.
- rows [read], [write], [nonatomic], [assign]
The number of rows in a matrix.
