Hello all. I have 2 very large Arrays (A = [10 20 30 ... 1800] and B = [1.385 1.419 1.527 .... 6.485]) of the same size. I have removed certain elements in B since they are not monotonic for my Interpolation function. How do I remove the corresponding elements in A as well? i.e. if if remove 4.834, in the Position 145 of the Array, how do i remove the element no. 145 in A as well. There are approx 60 such repeating elements in a single Array like B & I have 8 Arrays totally. Could anyone please help me with a solution. Thank you in advance

A=[1 2 3 4]
B=[5 10 15 20]
c=[10 20] %numbers to remove from B
idx=ismember(B,[10 20])
A(idx)=[]
