错误：“索引超出矩阵尺寸”

Question

The following code works when I run it on its own:

range = multi_sptime(100,end);
binary_input = binary_input2(1:range);
ssignal = signal(1:range);
signal = ssignal;% input current
clear input2 
clear binary_input2
dbstop if error

However, when I add this for loop:

neurons=[1,2,4,6,8,10,15,20,25,30,35,40,50,100,200];
for ncell=neurons
...

I get the error below:

??? Index exceeds matrix dimensions.
Error in int_idc20 (line 8)
ssignal = signal(1:range);

How do I fix it and what's going on?

Answer 1

First, I think you wanted to loop over the # of elements in neurons , so correct your for line with:

for ncell=1:numel(neurons)

and then depending on what you want use ncell or neurons(ncell) in your loop.

Second, range is a scalar that looks for multi_sptime row # 100 last element, and apparently the number it spits is larger than the # of elements is signal . Try to size(signal) to see what you have.
