cannot call or index into a temporary array

Hi, I am receiving an error "cannot call or index into a temporary array" for [Ro=c(1)(1)] and [Ri=c(2)(1)]. I have tried rewriting it as [Ro=cell(1){1}] but it does't change anything. Any advice on how to fix this error ?

c=textscan(fid,'%f%f%f',1);

Ro=c(1)(1); %column 1 row 1 of 'referencerawdata.txt'

Ri=c(2)(1); %column 2 row 1 of 'referencerawdata.txt'

theta0=c(3)(1);

MATLAB does not support cascaded indexing.

What are you trying to do? What is the structure of c, I.e. the ouput from

I am trying to call values of Ro and Ri from a .txt file structured as a table.

Use the "Import Tool" to interactively import the file. Then generate a script or a function from this automatically so you can reproduce what was done interactively.
