Octave: invalid use of script in index expression

Question

I want to use simple code ( plot.m) in Octave to build a drawing. My code is as follows:

printf('Plotting Data...\n');
x = -10:0.1:10;
plot(x, sin(x));

But I get an error message:

error: incorrect use of script ex1 / plot.m in an index expression error: called from the graph in row 3 of column 1

Could you tell me how to solve it? Thank!

Answer 1

I have the same problem to solve it

• changed script name
• removed previous scripts (which have the old name and contain the same scripts)
• write an octave, enter the file name "without m" (write "file" instead of "file.m")

here is my script and called it "xx.m"

syms x;
f = x^3 - 6*x^2 + 11*x - 6; 
ezplot(f)
xlabel("x") 
ylabel("y") 
title ("name")
grid on

xx run xx, .

-, " script"

• script . , my script "ezplot.m" "ezplot (f)", . , , script
• m , script , . , script.

Answer 2

: script.

plot(). script plot.m. Octave plot.m ... script! , plot.m script, . (, x sin(x) ), " script ".
