problem after new license

Hello,

Matlab had a notification for updating and new license on 6 December.

After updating and receiving the new license, I could not run a script that I had run before.

I wanted to read txt file and do some calculations.

-------------

Array indices must be positive integers or logical values.

Error in untitled (line 21)

fft_out_hdl = sqrt(hexData1.Var1.^2 + hexData3.Var1.^2 + hexData4.Var1.^2)/(2.^32) ;

---------------------------

I decided to use Matlab online.

My script works fine in Matlab Online, but I had this error in the new updated version.

Please give me suggestion how to solve the error

Thank you for considering this matter.

Best regards

Fatemeh

Can you share the script, so we can reproduce the error?

It is weird though, you get that error for the line in which there is no array indexing.

There might be more information in the error message, so please share the full error message i.e. all of the red text.

Thank you for your answer,

I shared only part of script that I had errors.

this code runs in matlab online, but doesn't run on my laptop after updating the license.

I think something is wrong in new version of matlab related to this

txt files are a column and 212217 rows.

% Define frequency axes
hexData1 = readtable('z_dataa.txt');
hexData3 = readtable('x_dataa.txt');
hexData4 = readtable('y_dataa.txt');
freq_axis1 = linspace(0, 2000, 2000); % 2KHz
xdata = hexData1.Var1.^2;
ydata = hexData3.Var1.^2;
zdata = hexData4.Var1.^2;
data_acc = sqrt(xdata + ydata + zdata);
% Plot xyz FFT
figure;
semilogy(freq_axis1, abs(fft(data_acc(1:2000) .* hamming(2000), 2000)));

In your workspace you have a variable named sqrt .

You need to

clear sqrt

[fatemeh abdi]

I don't have variable with named sqrt.

I only have po_sqrt, and also changed this name, but I have same error yet.

@fatemeh abdi, please share the output of this command -

which sqrt -all

[fatemeh abdi]

Thank you so much, I solved the error with writting both commands.
