I want to convert a single cell to a float number

i have a cell

celltest = {23.234,123.45};

And I want to convert the first number to float

something like this:

cell2float(celltest(1))

Answer 1

Should already be a float double. If not then,

double(celltest{1})

Answer 2

I'm confused. The way you have defined celltest, the first element is already a (double-precision) floating-point number:

celltest = {23.234,123.45};

class(celltest{1})

ans = 'double'

thank you. My Problem was I used the wrong brackets celltest(1) instead of celltest{1}

Answer 3

[KSSV]

celltest = {23.234,123.45}; 
class(celltest{1})

ans = 'double'

If it is double, nothing need to be done. If it is a string, read about str2num, str2double.
