MATLAB: Replication factors must be a row vector of integers or integer scalars.

Question

My coding is

depth = [0.01 1.5:1.5:30]';

w = 10 – 0.5 .* depth;

w(w<0) = 0;

a=829862;

b=21

c=a/b

W = repmat(w,c,1);

The result is replication factors must be a row vector of integers or integers scalars

Does any one can help me?

Answer 1

c must be an integer. Then, a solution:

depth = [0.01 1.5:1.5:30]';
w = 10 - 0.5 .* depth;
w(w<0) = 0;
a=829862;
b=21
c=round(a/b)
W = repmat(w,c,1);
