Hi,
is there an effective way to remove a row with a given index from a matrix ?
A = rand(10,5) A array([[ 0.15976517, 0.29574162, 0.21537014, 0.69341324, 0.68713389], [ 0.28992634, 0.89714962, 0.90299203, 0.22203182, 0.57831945], [ 0.23814492, 0.09436163, 0.67062125, 0.85923647, 0.64548996], [ 0.83215097, 0.85178335, 0.49873409, 0.59021905, 0.94631569], [ 0.5494401 , 0.08831399, 0.54776161, 0.10043204, 0.88260609], [ 0.90951225, 0.40967777, 0.78577964, 0.17414472, 0.59568316], [ 0.97491997, 0.76869065, 0.88901626, 0.69693058, 0.73576195], [ 0.25971704, 0.67759869, 0.42972164, 0.15069627, 0.13269489], [ 0.50012917, 0.5866074 , 0.32205757, 0.3347558 , 0.02555147], [ 0.66448744, 0.14755343, 0.09963282, 0.22277848, 0.35620143]]) ind array([0, 0, 0, 0, 1, 0, 0, 0, 0, 0]) A = A[ind==0,:][:,:] A array([[ 0.15976517, 0.29574162, 0.21537014, 0.69341324, 0.68713389], [ 0.28992634, 0.89714962, 0.90299203, 0.22203182, 0.57831945], [ 0.23814492, 0.09436163, 0.67062125, 0.85923647, 0.64548996], [ 0.83215097, 0.85178335, 0.49873409, 0.59021905, 0.94631569], [ 0.90951225, 0.40967777, 0.78577964, 0.17414472, 0.59568316], [ 0.97491997, 0.76869065, 0.88901626, 0.69693058, 0.73576195], [ 0.25971704, 0.67759869, 0.42972164, 0.15069627, 0.13269489], [ 0.50012917, 0.5866074 , 0.32205757, 0.3347558 , 0.02555147], [ 0.66448744, 0.14755343, 0.09963282, 0.22277848, 0.35620143]])
