Package Exports
- nv-uintyped-mat
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (nv-uintyped-mat) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
nv-uintyped-mat
- nv-uintyped-mat creat a mat-view of Uint-TypedArray
- fixed col-number and row-number (when init)
- the buffer can be SharedArrayBuffer
install
- npm install nv-uintyped-mat
usage
- creat\_uint\_mat(maxn,rownum,colnum=1,shared=true,empty=0,loc\_style=0)
- maxn is max-number/max-bigint permitted
- rownum is size
- if undefined, it will be calc from maxn,
- such as maxn = 9 (1001), size will be 16(10000)
- real\_size = colnum * rownum
- when colnum = 1(by default),its a series
- colnum >1 , its a mat
- buf\_size = Cls["BYTES\_PER\_ELEMENT"] * real\_size
- shared
- means if the bottom-buf is a sharedArrayBuffer
- empty
- means which number is used as empty,default is 0/0n
- used by clear
- loc\_style index for mat (colnum>1)
- 0: start from 0
- 1: start from 1 example
