Index exceeds the number of array elements

Hi,

I got the error written below.

Index exceeds the number of array elements. Index must not exceed 2.

Error in MasterPlan_RCC_V2_2(line 73)

CHG_step = CHG_step(1:Inputs_RCC.CyclesxcRate); % Based on how many cycles x C-rate

Line 73 is written in bold black.

Tolerance_D = abs(Files.PreProcessedData{idx}.Current_A - Rated_Cap*Inputs_RCC.cRate_DCH) < AcceptedErrorCurrent;

RCC_Step_CHG = {}; % Find the unique steps for the Discharge rates

for i = 1:size(Inputs_RCC.cRates_CHG,1)

Tolerance_C = abs(Files.PreProcessedData{idx}.Current_A - Rated_Cap*cell2mat(Inputs_RCC.cRates_CHG(i))) < AcceptedErrorCurrent;

% Record the unique step if it's CC step, charge and the C-Rate is the one from the pulses

if i == 1

CHG_step = Files.PreProcessedData{idx}.FlagUniqueStep(Tolerance_C & contains(Files.PreProcessedData{idx}.Mode, "C_CC"));

CHG_step = unique(CHG_step);

CHG_step = CHG_step(CHG_step > Cap_Check_Steps(end)); % Take the steps after the cap check not to repeat them

CHG_step = CHG_step(1:Inputs_RCC.CyclesxcRate); % Based on how many cycles x C-rate

RCC_Step_CHG = [RCC_Step_CHG; num2cell(CHG_step)];

This is for test protocol of battery. So, the protocol is shown below:

"CHG step (Charge step), C-rates are C/, C/3, C/2, 1C and 2C."

Charge Steps 3 cycles at each C-rate

C/5 with C/20 cut-off

C/3 with C/20 cut-off

C/2 with C/20 cut-off

1C with C/20 cut-off

"2C

with C/20 cut-off"

Can someone please help me?

My guess is that when you reach this line of your code

CHG_step = CHG_step(1:Inputs_RCC.CyclesxcRate); % Based on how many cycles x C-rate

CHG_step is an array of size (1x2). But the variable "Inputs_RCC.CyclesxcRate" is greater than 2. So you try to access elements of CHG_step that don't exist.

Thank you. Yes, you're right, but how can I fix or change it?

Since you are the only person who knows what's going on in your code, you are also the only person who can find a proper solution for this array access error.
