I want to import an array using the fread(), I wonder if I can use a prompt to get the type of file. I tried the following code, it works if I type the data type inside the fread() but its not working when I enter them from the prompt. I appereciate your help.
FID = fopen(filename, 'r');
if FID < 0; error('Cannot open file');
end
% Skip the header here...
prompt = {'Enter the type of input data (float,uint32,int16,double):','Enter the type of output data (float,uint32,int16,double):'};
dlg_title = 'the type of input/output';
num_lines = 1;
def = {'double','double'};
answer = inputdlg(prompt,dlg_title,num_lines,def);
data_type=strcat(answer(1),'=>',answer(2));
Data = fread(FID, Inf, data_type); % Choose the correct format!
fclose(FID);

data_type=strcat(answer(1),'=>',answer(2));
Should be
data_type = [answer{1},'=>',answer{2}]; % Curly brackets to access cell content!
