error using zeros in matlab

er = zeros(1, .125*N); % eigth rest
qr = zeros(1, .25*N); % quarter rest
hr = zeros(1, .5*N); % half rest
tr = zeros(1, .75*N); % three-quarter rest
wr = zeros(1, N); % whole rest

I get the error Error using zeros Size inputs must be integers.

Error in pleasework (line 49) er = zeros(1, .125*N); % eigth rest

When using zeros, the size should be an integer value. Please refer to the link below for more information.

@Esha Bhargava: you could put this as an answer, and I would vote for it.

[Akhil Sen Roy]

so whats the final answer ?? did you manage to solve it ?

[Jan]

John's answer is clear enough. The solution is trivial: zeros creates an array, and therefore the number elements must be integers. It is not clear what zeros(1, 0.125*N) should do if N is not a multiple of 8.

Answer 1

[John D'Errico]

I wonder, what are the odds that N is not an integer multiple of 8?

Zeros requires integer arguments. READ THE ERROR MESSAGE! If N is not an integer multiple of 8, then when you multiply by 0.125, you get a non-integer. So you need to think about what size you really need for this vector. If I had to guess, you might want to round up or round down, but this is your code, so you are the one who knows what you wanted to do.
