Accessing value in a cell

Hi,

I am trying to access value of a cell

>> a={'1,65,4,5'}

a =

1×1 cell array

{'1,65,4,5'}

>> a(2)

Index exceeds the number of array elements (1).

>> a{2}

Index exceeds array bounds.

Thanks

Look at what MATLAB is telling you:

a =
  1×1 cell array
  

How many cells does your cell array have? (hint: one)

What do you expect to occur when you try to access a non-existent cell?

Disregarding your buggy indexing, what is the expected output?:

• the character ','
• the characters '65'
• the number 65
• something else...

Hi Stephen,

expected output - number 65. The problem is that I have data from a file which has a={'1,65,4,5'}, I understand removing the quotes will solve it but I cant change the file that generates the data. It is a single cell, is there a way to convert it to 1x4 array?

Edited because of the comments:

a = {'1,65,4,5'}
b = str2num(a{:})
b(2)
