Hi,

A 6ya expert can help you resolve that issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

Good luck!

SOURCE: Singular matrix error

I had this problem as well...Were you working on a SinReg equation by any chance? I was able to do every other type of regression (Linear, quadratic, cubic, ect..) In order to get Sinusoidal regression you need to make sure you arrow down to the Period box when entering the equation, and fill it in with the number of items in your table of values (a ten item list means a period of 10). That was the fix for me, so hopefully it works for you!

Hi there,

On your Sharp EL-W535 press MODE and choose 1 for STAT. Press 1 for line (linear regression). You should see a table with three columns (x, y and Freq). Type in all your x values (press value =), then use your arrow keys to direct the blue block / cursor back to the top of the y-column. Type in all the y-values. Once you have finished inputting your data, press CHANGE.

To find the regression equation press ALPHA open bracket and equal. This will give you the y-intercept.

Press ALPHA and the close bracket button and equals. This will give you the gradient. You can also interpolate / extrapolate. Type in your x value press 2ndF and close bracket button, this will give you the y-value at x.

You can do the same to find x but use the open bracket button instead.

You must use the Statistics 2-var regression and choose quadratic regression.

Sep 16, 2014 | Casio Scientific Calculator FX-115ES PLUS...

What is the question?

Put your calculator in STAT mode (2-var statistics or regression )

Enter your data in two lists, preferably sorted according to the x-value

Choose a regression model from the ones available and get the calculator to give you the best fit.

However to see which regression model best fits you data you need a graphing calculator to draw the scatter plot, then superpose on the scatter plot the curve of best fit given by the regression model.

Once you accept a model as the most suited one, you can use the equation of the curve to predict a y-value given an x-value (what ever REAL LIFE meaning they might have)

Sorry to be the bearer of bad news, but the HP 10S calculator does not perform matrix calculations.

You have 9 variables A to F, M, X and Y. You can use them to store data, constants, calculation results, and other numerical values.

To store say the value 5674 in Variable A you press the key sequence 5 6 7 4 [SHIFT] [STO] A.

To recall the value stored in A (and use it in another calculation) you press [ALPHA] [A]. It will be displayed and you can do with it any calculation you want.

You can enter (store) data in Statistics modes

- Mode 2 is for standard deviation SD (1-variable statistics)

Open the Matrix function by pressing 2nd [x^-1]>EDIT.

Once Matrix is created, press [2nd][x^-1]>MATH>[1:det(] complete the matrix name and then press ENTER. If matrix is non-singular, you will get your answer.

Hi,

You want to solve the equation?

Like 1X+2Y=3

thank you

The problem is with the data. The calculator is telling you that your matrix is singular. Inverting a singular matrix is analogous to dividing by 0. Just as you can't divide by 0, you can't invert a singular matrix.

If you think that the inverse exists, double check the entries in the matrix.

Hello,

First stop the application that is running [2nd][Quit] or [Escape]

From Home screen

[Apps][Data/Matrix Editor/][3:new] name the data set when asked.

A table is displayed Enter the values in list c1 and c2 You can rename the variables in header.

When finished press [F5:calc]

In calculation type right arrow select 5:linReg in front of x enter c1, in front of y enter c2 and [enter] to save. the equation shows when you press [ENTER]

Hope it helps.

I know that it should make sense with no zeros , how can you change it?
