Hello,
I'm having difficulties separating character arrays. I want to split the char strings below and retrieve the numeric values.
'Time 12:57:33'
'Temp. T2 [deg.C] = 36.6'
'Solar Irradiance [kW/m^2] 0.857101'
Can anybody help me? Im new to Matlab and I know this should be an easy task, but im having quite some trouble with it.
Thanks in advance, greetings Boudewijn

c = {'Time 12:57:33'
'Temp. T2 [deg.C] = 36.6'
'Solar Irradiance [kW/m^2] 0.857101'}
regexp(c,'(\d*:)*\d*(\.\d*)*$','match')

Sorry,
The data is stored in a structure consisting of a several 69x1 cell arrays.
To refer to the second time value I type in;
solar.time(2,1)

str='Time 12:57:33'
out=regexp(str,'\d+(\.)?(\d+)?','match')

If your data are stored like:
v={'Time 12:57:33','Temp. T2 [deg.C] = 36.6','Solar Irradiance [kW/m^2] 0.857101';'Time 12:57:33' ,'Temp. T2 [deg.C] = 36.6','Solar Irradiance [kW/m^2] 0.857101'}
out=regexp(v,'[\d:]+(\.)?(\d+)?$','match')
out=[ [out{:,1}]' [out{:,2}]' [out{:,3}]']
