Computes dimensions for arrays and matrices.
$ npm install compute-dimsFor use in the browser, use browserify.
vardims=require('compute-dims');Computes dimensions of x. x may be either an array (including nested arrays) or a matrix.
varmatrix=require('dstructs-matrix'),data,d;data=[1,2];d=dims(data);// returns [2]data=[[1,2],[1,2]];d=dims(data);// returns [2,2]data=matrix([1,2,3,4],[2,2])d=dims(data);// returns [2,2]If an array element has a dimension inconsistent with other elements, the function returns null.
data=[[1,2],[1]];d=dims(data);// returns nullTo limit the number of dimensions returned, set the max option.
data=[[[1,2],[3,4]]];// 1x2x2d=dims(data,2);// returns [1,2]data=[[[1,2],[3,4,5,6,7,8]]];d=dims(data);// returns nulld=dims(data,2);// returns [1,2]data=matrix([1,2,3,4],[2,2]);d=dims(data,1);// returns [2]To run the example code from the top-level application directory,
