I am trying to make averaging for data saved in files named:pfoil_1_var_1_562474.raw, pfoil_1_var_1_562476.raw .......pfoil_1_var_1_562494.raw.
I have written the following lines but an error was generated
clc
clear
N = 6710*6; % grid size (number of points in raw file)
fid = fopen('pfoil_1_var_1_562474.raw','r'); % rb = read binary
data = fread(fid,N,'single');
fclose(fid);
start=8;
data1=data(start:length(data));
p=data1;
step=2
a=562476;
b=562494;
for i=a:step:b
fid = fopen('pfoil_1_var_1_',sprintf('%d',i),'.raw','r'); % rb = read binary
data = fread(fid,N,'single');
fclose(fid);
start=8;
data1=data(start:length(data));
p2=data1;
p=p+p2;
end
the error generated is
Error using fopen
Invalid permission.
Error in readsubspace_p (line 14)
fid = fopen('pfoil_1_var_1_',sprintf('%d',i),'.raw','r'); % rb = read binary
