in my program, i retrieve .csv data using load, but why is there an error when retrieving the data? . anyone can help me?

File1 = load('D:\OFAN SETYA RAHAYU\STMKG\30cm\random3.csv');

a=File1(:,1);
x=File1(:,2);
xq=min(x):0.075:max(x);

a = a-mean(a);
adet = detrend(a);

hello

how does the csv looks like ?

insteadd of load, use readtable , readcell, readmatrix or importdata

I attached the csv file.

i have used 'readtable' to call data from .csv. but after that there was an error when I searched for the minimum and maximum values of the data in one column. can u solve this?

this is the error message : " error to use min(x). Invalid data type. The first argument must be numeric or logical."

hello again

it worked fine with readtable , here I simply plot the first variable of the table and it's min value

T = readtable('random3.csv');
x = T.Var1;
plot(x);
[val,ind] = min(x);
hold on , plot(ind,val,'rd');
