How to delete NaN from column vectors ?

Hi,

I have two coulmn vectors, as you can see some values of y column are NaN and I would like to get rid of them and make it like x1,y1 so when for example second element of y column is NaN, I want also to get rid of the second element in x column

x = [1;2;3;4;5;6;7]
y = [1;NaN,5,NaN,12,15,18]

x1 = [1;3;5;6;7;]
y1 = [1;5;12;15;18]

Answer 1

[Walter Roberson]

x = [1;2;3;4;5;6;7]

x = 7×1

1 2 3 4 5 6 7

y = [1;NaN;5;NaN;12;15;18]

y = 7×1

1 NaN 5 NaN 12 15 18

mask = ~isnan(y);

x1 = x(mask)

x1 = 5×1

1 3 5 6 7

y1 = y(mask)

y1 = 5×1

1 5 12 15 18
